Abstract
An athletic shoe having an inner, forefoot-enveloping and gripping, elastic slipper sock for encompassing the forepart of the foot, the bottom of the elastic slipper sock being anchored to the sole assembly and being independent of the shoe upper, to move simultaneously with the foot and keep the shoe in tune with the foot. An extended toe bumper has medial and lateral cutouts astraddle the metatarsalphalangeal joint line to form vertically narrower portions. These cooperate with flexible mesh interconnecting portions of a bifurcated vamp in the upper, to effect controlled forefoot independence.
