Abstract: The present invention relates to a sporting and exercising device comprising an upper foot-receiving portion and a lower spring portion. The spring portion comprises an upper spring layer arched upwardly, a lower spring layer arched downwardly, an intermediate, generally flat and substantially elastic elongate member, a first connecting member for interconnecting first ends of the intermediate member, upper spring layer and lower spring layer, and a second connecting member for interconnecting second ends of the intermediate member, upper spring layer and lower spring layer. The intermediate member has two longitudinally spaced apart openings each having a peripheral contour and a needle extending across the opening from the peripheral contour thereof. Resilient shock absorbing bodies each have an annular groove for receiving the peripheral contour of one of the openings and a hole which opens in the annular groove for receiving the corresponding needle.
