According to the invention, the cushioning, shock absorbance, and energy return provided by a shoe is controlled by the surface area of cleats (30, 31 and 32) acting upon a resilient membrane (22 and 23) between the cleats (30-32) and receiving recesses or apertures (43-45) for the cleats (30-32). By providing cleats (30-32) of various lengths, the surface area of cleats (30-32) in contact with and stretching the resilient membrane (22 and 23) increases as more force is put on the sole of the shoe. This provides a desirable variation in support offered by the shoe so that more support is provided as more force is applied to the sole, and shock absorbance is maintained.
