Warning: Participating in any sport has certain
risks involved, which may cause bodily injury,
this is compounded even more for amputees
since they may not have the balance and
control with the prosthesis compared to a
normal leg/foot. Therefor, we advise you to
learn about the risks involved with each
activity and be sure to take the necessary
safety measures. The Alpine Foot alone, will
not guarantee athletic performance…. Though
with practice and the right tools, you can get
there!

SIZING ADJUSTMENTS
Small Frame –Length –275 mm Large Frame –Length –315 mm
Each frame is designed to
accommodate a range of four
sizes in 10mm increments. The
small frame spans from 275mm—
305mm and the large frame spans
from 315mm—345mm.
Adjust the foot length to match
the size of your ski boot. In some
cases this foot size will have an
exact match to the ski boot and
sometimes they will be slightly
different depending on the make
and style of boot.
Attention! This means you should
have your binding adjusted
specifically to your Alpine Foot by
a professional technician to
achieve the proper fit.

OUR
STORY
STARTS
HERE...
The Moto Knee2,Versa Foot2, VF2-HD, and Alpine Foot were created by Mike
Schultz, a professional snowmobile racer that lost his leg above the knee in 2008,
to an injury while racing. Unable to find prosthetic equipment to get back in
action and refusing to compromise, he created his own. His new designs allow
him to perform at a high level in all the sports he loves including snowboarding,
motocross, and snowmobile racing. BioDapt was established in 2010, to help
other amputees achieve their goals.
