Abstract
A high top athletic shoe has partial quarters terminating in spaced relationship to each other, in combination with a rear subassembly with inner and outer portions. The inner portion includes a substantially rigid lower counter portion and a soft, flexible Y-shaped upper rear portion forming a tendon engager, integral with but movable relative to the lower portion for flexing thereof between a forward foot-engaging position and a rearward foot entry position. The outer portion comprises a relatively rigid, U-support element pivotally mounted on both sides of the shoe, and movable between a lowered position beneath the counterpoint of the foot and spaced rearwardly of the inner portion, and an upper position snugly engaging the inner portion being retained in this latter condition by a connectable tensile strap extending around the U-support at the rear of the shoe.
