Abstract
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.
Claims20
A shoe having an upper, a midsole, and an outsole wherein said midsole comprises:
- an upper layer and a lower layer wherein said upper layer has a bottom surface and said lower layer has a top surface, said lower layer being located substantially between the outsole and the upper layer, the bottom surface of said upper layer substantially facing the top surface of said lower layer, said upper layer further having a heel region, said bottom surface of said upper layer further having at least a first convexity, a second convexity, and a first concavity, said first concavity occupying substantially all of said heel region of said bottom surface, and said upper layer and said lower layer each having a density wherein the density of the upper layer is denser than the density of the lower layer.
A shoe having an upper, a midsole, and an outsole wherein said midsole comprises:
- an upper layer and a lower layer wherein said upper layer has a bottom surface and said lower layer has a top surface, said lower layer being located substantially between the outsole and the upper layer, the bottom surface of said upper layer substantially facing the top surface of said lower layer, said upper layer further having a heel region, said bottom surface of said upper layer further having at least a first concavity and a second concavity, said second concavity occupying substantially all of said heel region of said bottom surface, and said upper layer and said lower layer each having a density wherein the density of the upper layer is denser than the density of the lower layer.
A shoe having an upper, a midsole, and an outsole wherein said midsole comprises:
- an upper layer and a lower layer wherein said upper layer has a bottom surface and said lower layer has a top surface, said lower layer being located substantially between the outsole and the upper layer, the bottom surface of said upper layer substantially facing the top surface of said lower layer, said bottom surface of said upper layer having a single convexity and a single concavity, and said upper layer and said lower layer each having a density wherein the density of the upper layer is denser than the density of the lower layer.
