The present invention provides a shoe having a multi-layer, multi-density midsole where the surfaces between midsole layers have one or more convexities and one or more concavities which collectively contribute to simulating the effect, and imparting the fitness benefits, of walking on a sandy beach or on a giving or uneven surface regardless of the actual hardness of the surface.

Shoe

A shoe having a toe region, a middle region, a heel region, and a multi-layer, multi-density midsole wherein an upper layer of the midsole has a bottom surface that has a longitudinal convexity and a longitudinal concavity, the longitudinal convexity typically occupying a substantial portion of the toe region or a substantial portion of the toe region and middle region, and the longitudinal concavity typically occupying a substantial portion of the heel region, the longitudinal convexity and the longitudinal concavity collectively contributing to simulating the effect, and imparting the fitness benefits, of walking on a sandy beach or on a giving or uneven surface regardless of the actual hardness of the surface.

A shoe having a toe region, a middle region, a heel region, and a multi-layer, multi-density midsole; the midsole being comprised of at least a shank and a lower layer; the bottom surface of the shank having at least one longitudinal concavity and at least one longitudinal convexity, the longitudinal concavity typically occupying a substantial portion of the heel region and the longitudinal convexity typically occupying a portion of the middle region. Collectively, these elements contribute to making the shoe appropriate for both walking and higher impact activities such as running, and simulating the effect, and imparting the fitness benefits, of use on a sandy beach or on a giving or uneven surface regardless of the actual hardness of the surface.
