A shoe includes an outsole which has a flat tread portion and a peripheral member that extends upwardly from the periphery of the tread portion. The peripheral member has an upper section and a lower section. The tread portion and the lower section of the peripheral member cooperatively define a receptacle. A resilient cushioning wedge is adapted to be received in the receptacle and has an upper base member with a top side and a bottom side. The bottom side is integrally formed with a plurality of downwardly extending cushioning elements which have free ends glued to the tread portion. The base member has a periphery glued to the peripheral member. An insole is glued to the top side of the cushioning wedge. The shoe further includes a vamp which has a bottom end sewed to the insole and a bottom periphery sewed to the upper section of the peripheral member.
