WHY DOES IT HURT IN MY SKIBOOT?

As previously described , every foot is unique, but when it comes to skiboots, the foot has to accomodate itself to  the skiboot shape and the rigours of the shell stifness during your ski holiday , no matter if it’s -20° or +10°
This section  will help you to learn more about your feet , toubleshooting your particular problem and the solutions TOTAL FEET can provide to make your feet happy…
Reminder
Our feet  are the only  segment linked  from our body to the ground. They support entirely our body weight  and enabling  us to move around .In a standing position , the foot is linked to the grou nd through 3 points :

Heel : supports 50% of our body weight
First metarsal head ( behind the big toe) 30%
Fifth metarsal head ( behind the little toe) 15%

Each foot has 3  different arch designed to guide our feet through the different contact phase on the ground

The internal arch: runs from the heel to the big toe : its function is to provide balance throughout the gait, absorb  and  match the terrain
The external arch: runs from the heel to the little toe : its function is to provide guidage to the foot structure thoughout the  whole gait  walking ,or running
The tranversal arch:  runs from the  first to the little toe : its a propulsive arch enabling the forward toe off motion and to propel from one foot to the other

Each foot works autonomously relying on the informations registered by thousands of sensors located on the plantar surface of your foot , enabeling  the lower limb and foot  muscles to adapt  instinctively ( proprioception)
In layman’s terms the foot functions just as an universal joint on your car and the foot’s arch as your shock absorbers and springs

 WHAT’S YOUR FOOT SHAPE ?

Find out  more about your footshape
Just have a look to your humid footprint  after getting out of the shower or bathtube
We  categorize in 3 foot shape :

THE STANDARD OR “MEDITERRANEAN” FOOT

C’est la forme de pied typique des pays méditerranéen  ( France, Espagne, Italie, Autriche, Allemagne, Belgique etc..)  . La taille moyenne est généralement comprise pour l’homme entre 39  et 42 ; 36 à 38 chez la dame. Sa structure  est plutôt étroite :

  • talon fin , tendon d’achille saillant et étroit .
  • Cheville fine avec des malléoles interne et externe saillantes
  • Une charpente musculaire homogène avec une voute interne bien formée, flexible et tonique
  • Un cou de pied généralement légèrement cambré.
  • Un avant pied fin ou moyen

C’est le pied idéal pour les mocassins italien, la forme  chaussure de ville  des années 50 à 80

THE FLAT FOOT

The scandinavian or north american foot . It’s a flat foot with a weak muscle structure, creating an unstable pattern.  It’s the weak foot  with its toll of sprain ankles, twisted knees…
The muscle’s structure is much more elastic . Our way of life has drastcially altered our walking, sports habits as well as as our footwear in most of  the industrialized countries around the world , this foot shape tends to become more more unversal.
The average footsize ranges  from 42-45  ( UK 8-11)  for men’s ; 38-42  ( UK 5- 8)  for women’s depending of the continent

The overall foot shape in rectangula  with a wide -extra wide forefoot
The heel section is well rounded with less apparent achille’s tendon
The ankle section tends to fall in  on the inside, the inside ankle bone sinks in

The overall lower foot muscular structur is relatively flexible, the plantar muscles are looserthan on the normal foot with a lower inside arch

Known as the “sneaker generation foot”, mostly  wearing soft shoes with a  wide forefoot section avoiding any conflicts or aggressiveness

HIGH ARCHED FOOT

The high arched foot is a rigid foot with very little contact surface. This will be limited to the base of the hell and the forefoot section behind the metatarsal heads. The whole muscular foot body is in constant strain: this affects the foot structure mostly in the instep : high and rigid.
The inside arch is strained, with in somes case the hammer toes
The tranversal arch is convex with calluses under the mid metatarsal heads
The most toublesome footshape in ski bootfitting: this foot isn’t compatible with the last of most  “normal” skiboots as well as with the mechanical constraints theskiboot will aplly on the foot : instep buckles tighthning, putting the skiboot on taking it off after a cold ski day…..

The answers x

Normal Foot

This is a very annoying sensation feeling the heel lifts while skiing  at a relatively high pace or during while edging = lack of ski control , impossible to edge properly. Usually this doesn’t only affect the heel but also the ankle bones as they are not well adjusted in the liner ankle padded pockets.

When  we try to lock the heel down by overtightening the buckles, the foot tends to fall asleep  due to lack of blood flow
The professional skiers, racers   can be affected by   a heel bursitis appear on the outside section of the heel

Solutions for a heel lifting in skiboots

  1. Check  that your skiboots match your proper footsize: you might , or the shop must have been too generous while selecting your skiboots. You may have to select a new pair of appropriate skiboots in the right size
  2. Get a pair of custom  insole  fitted properly to match your foot. This will spread evenly your bodyweight pressure on the whole length of your foot, provide ithe ideal arch  non corrective  support and the proper heel cup hold  They advantagously replace the standard footbed made to fit anybody
  3. Modify your existing liner to your footshape, or replace them with a custom made liner such as INTUITION thermo liners for leisure skiers, ZIPFIT on PU foam injected liners for advanced, racers
  4. In the case of bursitis, a complete assessment of the liner & shell volume will determine the different solutions : shell grinding in the heel section and exoanding the shell ( racing, low volume shells ) or   modifying the liner structure  by adding with a custom o ring padding and sewing  ( frequent  with touring skiboots)

PRESSURE ON TOP OF THE INSTEP

As soon as you tighten the  shell buckles , your toes start to feel numb and you get cold feet

Solutions

  1. Make sure yoiur skiboots  match your foot size and foot shape
  2. An inappropriate buckle tighteness on the instep  will affect the blood flow to the upper body by reducing its volume. Consenquently the toe area  will start to go numb  , and cold feet symptom will appear in no time. Therefore everyday yuo’ll have to fine adjust the pressure on the lower part of the shell. Use the micrometrical buckles and select the settings on which you’ll have an  EVEN   pressure on the top of the instep .In some cases, we may modify the ratchet length. After lunch, as the outside temperature has increased, fine tune your buckle adjustments
  3. Internal tongue modification . TOTAL FEET is equipped with a professional shoemaker sewing machine.This enables a lots of liner or tongue modification in order to make your skiboots more enjoyable without having to switch the liners to a custom made

The shell volume  match your feet, but after an 1 hour of continious skiing, you feel a cramp under the in side section of your foot . You have to loosen the buckles, shift your foot around in the skiboot, inorder to ease this uncomfortable sensation.

Solution :

The shell might be a bit too close to your foot on the internal section of the skiboot. This is common to most performance and racing skiboots. This low volume last is desigbned  to provide the skier a precise edging and rsponsiveness 

  1. Get  a proper pair of custom made footbeds that will match your arch providing a natural support such as a guardrail. This must not be a corrective support in this area
  2. Shell fitting  modification of the inside section by expanding sligthly this area : the arch is a muscle, this will provide extra space for the muscle to function properly

With the standard foot , usually this pain is located  on the little toe ( behind the fifth metarsal head). A painful outgrowth when applying pressure. Development of a  exostosis .

This a very common problem affecting skiers who are all day long in their skiboots such as  skipatrollers, instructors racers of all level. In the most severe cases, the skier must stop putting his skiboots on  for a determined period from 15 days to a month. Quite annoying for a ski instructor or a racer when the season is in full swing.

  1. Poorly fitted skiboots  ( too big, not enough lateral room on the 5th metarsal head) ski instructor using  high performace skiboots while teaching snowplowing to beginners
  2. wrong shell size

This doesn’t appear right at the beginning, but usually just after the Christmas break, they are in pain …….
Solution :

  1. Get a pair of custom  insole  fitted properly to match your foot. This will spread evenly your bodyweight pressure on the whole length of your foot, provide the  arch  non corrective  support and redritribute the pressure on the tranversal arch
  2. Shellfitting ( local shell grinding + shell expanding ) creating a cavity in which the injured area won’t be in conflict with the shell while skiing and edging
  3. ​Liner modification : 2 ways :  Modification of the existing liner by openning up the liner, adding a oring padding and sewing it back . Making a custom made liner ( usually a thermo molded liner  with extra  protective padding before molding and then modifiy it to relieve the pressure if necessary)

If your foot looks like this : then it’s too late  !!!!!!!

We have to get in “Survival mode”  ( for ski pro’s)

​1- Slash a pair of skiboot to end the ski season. Le liner must be cut open around the area . Reinforced with padding to allow  provide no direct contact + local grinding and shell expandition

2- For ski pro’s : teach beginners and low intermediates classes with mountaineering boot ( wider and more forgiving boots)

3- medical  follow up as well pharmacy for oitment treatment

4- When not in skiboots, try to wear loose fitting shoes , bare feet at home
5- During the fall period, start looking for the most siutable skiboot and a proper fitting by a renownwed bootfitter

Main causes

  1. Poor ski boot selection   :  shells too narrow  , or really too big ( must must overtighten the buckles in order to carve a turn
    Ski pro’s teaching with race last skiboot  low classes ( please don’t show off, your feet will be thankful)
  2. poor innerboot fit  

SOLUTIONS

1-LA CHAUSSURE  Si la coque correspond à votre morphotype et que la taille soit adaptée

  • 1-Travail de la coque ( fraisage ponctuel de la coque + déformation sur la zone) afin de créer un espace où la zone douloureuse ne sera pas en conflit avec la coque
  • 2-Modification du volume chaussant ( évidement du chausson, on enlève le rembourrage, remplacement par une mousse plus souple )  remise en forme du chausson+ couture
  • 3- Confection d’un chausson sur mesure en protégeant le pied dans la zone douloureuse avant moulage

2- LE PIED

Il existe de nombreuses  solutions para médicales , mais voici une recette de grand -mère 100% naturelle qui m’a été donnée il y a 6 ans, que je recommande à toutes les personnes  après avoir modifiés les chaussures qui  sont affectées par ce problème. Le retour est excellent , presque miraculeux.C’est aussi recommandé  à titre préventif

Bain de pieds (ou mains) au céleri  3  fois par jour, faites un bain de mains ou de pieds pendant 20 à 30 minutes dans :
– une décoction chaude de céleri-rave avec ses branches (250 grammes environ pour 1 litre d’eau froide que vous ferez bouillir pendant une petite heure); après ce bain, séchez immédiatement les parties atteintes avant de les envelopper dans un lainage.
Au bout de trois jours, vos engelures auront miraculeusement disparu. Mais le côté encore plus extraordinaire de ce traitement (et pour lequel aucune explication médicale rationnelle n’a pu encore être donnée) c’est qu’il y a également neuf chances sur dix pour que, par la suite, vous ne souffriez  plus d’engelures

Pensez à hydrater vos pieds Le soir apres votre douche ou bain , prenez 2mn afin de réhydrater la peau et capiton plantaire. Tout au long de la journée enfermées dans la chaussure de ski , ils souffrent plus que vos mains dans les gants.

The flat foot

he most  commom problem affecting the flat footed skier also known as pronation

Right at the start of turns the ,inside ankle bone  comes in conflicts with the liner and shell . as you edge the ankle will rotate towards the inside and downwards. In this motion, the ankle bone shifts down getting out from its ankle padding. This hgappens with every turn. By the end of the day , the inside ankle hurts or has swollen. In order to avoid this , a lot of skier will buy a bigger sized boot or get their shells expanded to avoid this….with some success but it lasts only a couple of days: as the bottom of the foot isn’t stabilized, the ankle still rotates and the ankle bone shifts downward

Solutions.

  1. First of all  get a pair of custom made footbeds . TOTAL FEET will make a footbed using the latest techiques in sports orthotics . A negatif of your feet on vacuum pads specially designed  to provide a full mathing negatif of your feet in a full weight bearing position. This footbeds will enable the rear section of the foot to stand in its nominal position while skiing. The natural ach support will provide the foot a balanced position while edging thoughout your turn.
  2. Shell fitting : Your foot might require some shell fitting, in order to match  the medial part of your foot as well as the ankle bone. Grinding or shell expanding can de done.
  3.  Standard liner modification or Custom made liner.  Often , your inside  ankle doesn’t match the standard ankles pads in the standard skiboot. There fore we may modify your existing liner or make a full custom made liner . A complete range of liners is available at TOTAL FEET  depending on your skiability, season skidays  and shell. Even though the 2 first solutions are mandatory before making a liner

As I previously mentionned, the flat foot is a weak foot structure. While skiing this laxity affects the stability of the muscular strucutre of the lower part of the foot . The  transversal arch  ( which runs from the big toe to the little toe) is subject to opposite forces than the ankle. The foot set itself in a corkscrew motion
Just as for the inside ankle bone, most skiers will get their skiboots expanded , but the problem remains, even if you ski all day long with the lower buckles in an open position ( it increases!!!) .

Solutions:

  1. Get  a proper pair of custom made footbeds that will match your arch providing a natural support such as a guardrail. This must not be a corrective support in this area. The orthotics will  provide your foot a equally distributed weight pressure avoiding the forefoot to collapse while edging
  2. Shell fitting in the forefoot region. A laterall expoansion of your shell will  relief the pressure on the external arch  ( which runs from the 5th metatarsal to the heel) and allow the tranversal arch to perform as naturally as possible while skiing.
    Warning: we must expand the shell as naturally as posibble to match your feet and not turn your shell into a wide shoebox….

As previously described , every foot is unique, but when it comes to skiboots, the foot has to accomodate itself to  the skiboot shape and the rigours of the shell stifness during your ski holiday , no matter if it’s -20° or +10°

I’m knocked Knee, can’t keep my skis running flat

 

A typical  flat footed problem : the lower limb laxity has an effect on the whole  lower limb muscles chains. TOTAL FEET will compensate this  natural difficiency ,realign the skiboot in order to provide the foot the best natural contract on the ski surface.

Solution 

  1.  Make a pair of custom made footbeds that will provide the natural stance your foot requires in the skiboot
  2. . TOTAL FEET is equipped  with the latest technology  in terms of canting assessment and skiboot modification. Your footbeds will be corrected on  the rearfoot section . bottom section of the shell will be individually routed or wedge canted  from 0.25° to 3°

High arch foot

Impossible to carve correctly a turn, I always need to unweight my foot. 

This is the most common problem skiers with hich arched feet have encountered. Some of them just stop skinng, sit down , take their skiboot off, massage their forefoot and take off until…the next cramp

the skiboot shell will apply pressure on 2 particular areas the high arched foot doesn’t enjoy: volume restriction in the forefoot  and tranversal arch.
instep compression  from the tongue onto the instep

Solution 

 

  1. A specific footbed made to fit the high arched foot.TOTAL FEET has  elaborated sports ans skiing orthotics for the high arched footThey are made with  a shorter arch support providing the rearfoot support and softer material, in the metarsal metarsal  may be added in order to provide de transversal arch balance while edging. If you are suffering a Morton syndrom usually located between the 2nd,3rd metatarsal  a special support may be added as well as shell fitting in order to provide  comfort in the forefoot
  2.  reduce the pressure on the instep and forefoot. When tightening the buckles, the shell applies too much pressure on the instep , the foot will become numb and affect the blood circulation by installing on your existing liner a custom  made tongue ( INTUITION or foam injected) Longer ratchets and lowerîng the internal footboard to provide the forefoot extra volume
  3. Shell fitting  The forefoot  section  can be expanded to allow more room for the transversal arch

A new skiboot should also be considered. For this specific foot TOTAL FEET recommends  a 3 piece shell structure such as Full Tilt  , Nordica Arrow , Dalbello Pantera. A  unique shell design  for  a even pressure on the instep. A custom thermo INTUITION liner will add comfort and warmth. Racers and advanced performance skiers will choose between a foam or ZIPFIT  custom made liner

Solution 

Some skiboot  need to be modified mostly   on the outside ankle bone . The ankle bone is out of this liner  cushioning. Shell grinding and a expansion will solve this problem

The high arched foot has a shorter achille tendon limiting the forward flexion and knee work

Solution 
Shell fitting : grinding the heel cup and lower section  will unease the pressure around the achille’s tendon. A  5-8mm heel wedge maybe added on the foot board to reduce the strain of the tendon while skiing

Just as the flat foot problem : the lower limb stiffness has an effect on the whole  lower limb muscles chains. TOTAL FEET will compensate this  natural difficiency ,realign the skiboot in order to provide the foot the best natural contract on the ski surface.

Solution

  1. Make a pair of custom made footbeds that will provide the natural stance your foot requires in the skiboot
  2. . TOTAL FEET is equipped  with the latest technology  in terms of canting assessment and skiboot modification. Your footbeds will be corrected on  the rearfoot section . bottom section of the shell will be individually routed or wedge canted  from 0.25° to 3°

Common problems

The bump itself is partly due to the swollen bursal sac or an osseous (bony) anomaly on the metatarsophalangeal joint This deformity due to tigh wearing streetshoes as well as high heels for a long period   becomes very painful  for mostly women  in their 50’s. It could be also congenital for both men and women and become quite annoying in their 30’s.  This foot shape won’t allow any pressure on the medial part of the foot particularly around the big toe ( standing or walking)For every day use, the soft leather shoes as well as sports shoes can be soften by expanding  around the first metatarsal area to unease the pressure while wearing the shoes.. with a special leather softening solution  or by the expert hands of a shoemaker and machine

With ski or touring boots as the shells are made of a stiff material, the work has to be done on the shell as on the liner

Solution for hallux valugus in ski boots

1.       Total feet will make a pair of custom made skiboots to match your feet
The right  shell selection is a must: enable sufficient forefoot volume without affecting the heel grip or the overall skiboot performance to your skiing ability. Then the shell will be altered to your feet’s specification by local grinding and shell expanding on the metatarsal’s location : this will avoid any foot conflicts  on the first  metatarsal’s foot joint while edging and skiing

2.       Custom made liner specially made to your feet with a extra padding  added to the first metatarsal joint to relieve the pressure on the joint. This process will take a good 2h30 , but the result will be above expectations

I’VE GOT THICK CALVES, FINDING SKIBOOTS I CAN CLOSE THE UPPER BUCKLES  IN MY SIZE IS….HOPELESS

As all the skiboots have been made to fit the”normal feet” and calves to a certain extend, people with oversized calves are handicaped with skiboot fitting .let’s have a closer look to  the different options by gender

Women: The calve’s structure is different than the men’s: The muscle volume is more consistant in the lower section up to 5cm above the ankle bones. This is why most of the women’s skiboots wil have a lower collar and around the   top section to allow the calves muscles to “ breathe” while skiing. In most cases, the side pressure  on the calves when buckling up the top  skiboot is soo strong, the women end up skiing with the top buckles open or with oversized skiboots in order for then to be able to fit their calves , the ankle isn’t held properly .This has a direct impact on your ski performance: lack of ski control, absence of power edging
Solutions for fitting  thick women’s calves

Total Feet will make a pair of custom made skiboots to match your feet. This relys mostly on modifying the upper collar of the skiboot.

  1. Make the top collar match your calve in terms of shape and support.The top collar will have to be grinded, trimmed, and the top buckles changed for longer ones
  2. A liner change might be necessary for a thermo custom made liner with an overlapping closure avoiding the tongue uncomfortable side compression

Solutions for fitting  thick men’s calve
Generally , men’s either have a  hypertonic calve muscle requiring a greater volume without compressing the calves muscles and creating cramps while skiing or then just a voluminous calve. In both cases , the approach and work solutions will be similar to the women cases

Solution

Atomic Waymaker  carbone 130   with a very wide forefoot area
Extra forefoot width expansion

Cuff: : Lower the height  of the cuff   between 10 to 15mm . Special XXL cuff ratchets

Making of a thermo  INTUITION LUXURY liner . This liner will mold around the shape of your leg without compressing the calves ( like an upside down bottle of Chianti wine )

DURING THE  WINTER SEASON, MY FEET TEND TO GET NUMB. I CAN’T FEEL MY TOES

This is the  major  complaint  for customers during their ski holiday. They try to find a warmer  holiday destination alternative. But equipment and technology has drastically improved enabling them to get back on the slopes no matter if the thermometer is below 0° or during spring skiing
Let’s have a closer look to the causes of cold feet  in skiboots

Mechanical :  This is the most common. The skiboot is inappropriate to your foot shape or too big.The shell creates a pressure onto your foot by a pressure point often on top of your instep  ( overtighting the buckles ) reducing the natural blood flow, making the lower forefoot section to turn numb . This pressure point could be also on the lower section under the inside ankle bone . The liner padding causing a pressures restricting the blood flow from the lower leg to the

Natural :The human body must constantly regulate it’s internal body temperature ( lungs, liver, brain , genitals ) to a stable temperature of 37,5°. The outside environement will have an impact on our  body thermo regulation : sweating in a warm enviromment , or in a cold environement, the blood flow reduction to our extremities ( fingers, toes, ear lombs, nose ): the capillary vessels in the end section of our limbs are contracted limiting the blood flow . The supply is then requited to supply a minimal flow= life without heat . That’s why we get cold feet.This is known as Raynaud’s phenomenon a discease affecting mostly women
Remedy to cold feet in ski or touring boots

  1. For starter’s get the right shell to match your foot shape.The shell must allow a nice fitting ywothout any pressure bpoint that could affect your blood flow. This can be modified by shell work such as shell exoansion or grinding.
  2. Total Feet will choose the proper shell to your feet and skiing level specifications . It will be then modified  in the in step  or heel section to match your foot structure
  3. A thermo footbed will be custom made to your feet in order to improve the thermal isolation on the lower  foot section
  4. In some cases , a custom made INTUITION liner will provide the best insulation and fit around the foot and an unrivalled comfort  in the toe room.

 

Nowadays, technological improvements mostly in the NICAD and Lithium  batteries and cbles and connections have made heating much more reliable in  skiboots : integrated heating elements on your  ski orthotics or integrated in ski socks. You’ll be able to enjoy skiing no matters what the outside conditions are and keep your feet happy no matter if you’re a occassionnal skier, or ski instructor, ski patroller. This comfort can be the same sensation as comparing this with your car’s A/C. You’ll be asking yourself how you’ve managed without until now…

How does it work ?

A large oval heating element provides effective anatomical coverage of toes The Hotronic FootWarmer Power Plus  batteries offers three base level settings for comfort and warmth maintenance. A fourth setting offers a quick, extra blast of heat when needed.Simply slip the heated insoles into your footwear and plug them into the rechargeable Battery Packs. Thenfine tune the temperature setting to 1, 2, or 3 for comfort and warmth maintenance.

FOOTWARMERS by HOTRONIC have established as the leading brand in footwarmers over the years.I’ve mounted my first footwarnmer in 1979 in Canada, and relied on them ever since. The new generation will allow a 10000 recharging cycles and a 3 year manufacture warranty.

 

Heat Socks by LENZ

A  true reliable  innovation  The heat element and connectors are integrated seamless in the sock . A small Lithium battery is clipped to the top cuff of the sock: no more loose cables external batteries. The socks are machine washable and can be bought seperately. This sytem is well used by racing skiers who have to stand long hours in the racing suits  durin g training sessions or during the freezing cold  winter days.
You will enjoy this , if you’ve looking for a simple easy to use heat system in your skiboots
