ABSTRACT:
A snowshoe incorporates a semi-rigid boot housing assembly which encloses the boot of a user on either side and bottom of the foot, and an integral heel crampon assembly which precludes deflection of the snowshoe flotation member and heel crampons by ensuring that the downward force of a user's weight is transmitted directly to the crampons whereby the crampons remain perpendicular to the snow surface, the boot housing assembly extending to the heel area and upward to the ankle area and including an adjustable heel stop assembly attached to the housing for ensuring that the ball of the foot is positioned directly over the snowshoe axle, the housing assembly having semi-rigid side walls which extend the lateral rigidity to the ankle area, and provide a tension member to resist foot movement during descents, the housing walls being designed to comfortably restrain the foot using an instep clamp assembly, the boot housing assembly including a width adjustment system which allows the user to pre-set the proper width in the "ball-of-foot" area and having a rugged ratchet strap assembly with actuating lever which allows the user to exert substantial binding force toward the heel stop assembly.
