The subject device is an auxiliary apparatus designed and structured to be appended to the lower part of a cane or crutch so that the user may have additional mechanical means to help lift his leg or foot with the aid of the crutch or cane. The device comprises in general an L-shaped frame member, the lower leg of which functions essentially as a stirrup upon which the foot can be placed, while the vertical is adapted, when so used, to be rested against the lower shank of the cane or crutch. An adjustable U-shaped collar is pivotally mounted to the upper leg of the L-shaped member serving to affix the L-shaped frame to the crutch shank. By pivotally mounting the L-shaped frame to the collar member, the L-shaped frame member can be pivotably moved to a position that is retracted upward out of the way when not in use.
