Racers today needs to drive precisely their 2 skis, they need to feel the terrain to be precise on the ski : Precision is as important than power. Metas are key for Precision, if the shell is too wide you lost precision, if the shell is too narrow, it is painfull so you can't feel the terrain. You need to have the shell at your exact foot shape : you need to have the boot molded to your foot shape. This is exactly what our race technicians do for our racers ; this is exactly what Custom Shell will do to your boot. We develop a specific plastic material Kaprolene that allow us to mold the boot around the foot. This is patented by Salomon. For the Consumer this means he can now pretend to have the top performance boot without foot pains : we're adding comfort to performance.
