Yes. Custom footbeds are very important to align and support our feet when skiing.
We are designed to walk or run, not stand hip width static in a plastic shell. So, understanding what the human bio mechanic requires when skiing is very different to what it requires when walking.
Our feet naturally Pronate or supinate and to allow this to occur when skiing simply creates delay in the feet controlling the ski and will lead to fitting problems like sore ankles or your feet tipping and moving around in the boot.
The Sidas ConForm’able foot bed system that we use at The Boot Lab casts and supports the fore foot as much as it does the rear of the foot, creating whole foot support with neutral alignment for the feet to stand in a boot and on a ski with more feeling, response and comfort.
