Abstract
A foot for a crutch has a ground contact portion with a variable camber. The camber angle changes from at least one of a front edge or rear edge of the variable camber, to a maximum camber. In embodiments, the camber increases from the at least one of the front edge or rear edge to the maximum camber region, and then decreases to the other of the front edge or the rear edge. In embodiments, a foot can have two regions of different cambers laterally disposed from each other such that only one of the two regions contacts the ground during a step at any given time.
