ABSTRACT:
A custom-fit ski boot orthotic which efficiently transfers movement of the foot to the edges of the skis. The orthotic has a substantially rigid base plate attached to a rigid heel post. The base plate has an arch portion 20-40% shallower than the skier's actual arch which permits the limited movement necessary for foot comfort, without any significant loss in transfer efficiency. The base plate also has a heel cup portion to prevent heel roll. The orthotic of the present invention may be used as an insert or be built into the footbed of a ski boot.
