As we indicated in a previous article, **nearly 90% of skiers experience pain in their ski boots**. Among the most common are ankle pains, particularly around the ankle bones. The classic symptom for a skier is feeling the boot rubbing against the ankle bone. **Where do ankle pains in ski boots come from?** The ankle allows for angulation and power transmission from the leg, while adapting to the terrain profile. Inside the boot, it needs space while being adequately supported. Ski boots are rigid and have a high shape. **These two characteristics promote compression and friction**. When you feel pain in your ankles or ankle bones in your ski boots, **it mainly comes from the conflict between the foot and the boot**. The protruding ankle bones, the ankle bones, are even more prone to this compression and friction phenomenon, especially if you wear ill-fitting boots: - If your boots are too small, **compression will cause pain**. - If, on the contrary, your boots are too large, **your ankle will "float," leading to repetitive rubbing**. **How to remedy ankle bone pain in ski boots?** There are 4 possible actions: **Thermoforming of the liners** Some ski boot models have removable liners. A professional can, by heating the liners, **adapt their shape to your feet**, like a mold or a second skin. This technique also allows for creating volume in certain areas by placing patches where needed to free up space once removed. **Bootfitting** Bootfitting allows **reshaping the boot shell at compression points to achieve optimal comfort**. From a ski boot made for a universal foot, you will transition to a fully personalized boot. You should also consult a professional who, after understanding your needs, will conduct a detailed analysis of your feet to identify the possibilities of adapting your boots through bootfitting. **The areas to be adjusted are heated and then deformed using jacks to create the necessary spaces**. **Insoles** Opt for insoles **suited to your arch**. They will be a great comfort aid. There are three types of arches: physiological or neutral arch, flat arch, and high arch. Regardless of your foot type, **the key is to maximize the contact surface to support and control your foot**, while providing more stability. After taking your footprints on a specific machine, they are then transferred to the insoles. **Your comfort is immediately improved by increasing the interface between your foot and the ski boot**. **Opt for ankle bone protection** Our GelProtech Ankle Guards: These devices are inexpensive and transferable from one pair of shoes to another. They consist of ankle guards with silicone gel discs positioned at the internal and external ankle bones. **This way, they are protected from the pressures they may undergo in the boots during skiing sessions**.
