An air cushion shoe base has a thick sole and a thick vertical rim across which are formed air tight partitions and an insole. Each partition has a small valving orifice for flowing fluid between sections on opposite sides of a partition. A valve is provided within the rim, and the valve has a central body with a long valve orifice and lateral extensions for joining the body to an inside of the rim. A T-shaped welt extends around an upper peripheral area of the rim and insole for joining the cushion base to a shoe upper.
