Three layer shoe construction with improved cushioning

A three-layered shoe construction comprising:

• an outsole having an exterior face, an interior face, a proximal side, and a distal side, the exterior face including a first section, a second section, and a third section, each of said first and third sections including a plurality of raised ribs, the first section further including a plurality of groves which intersect said plurality of raised ribs in the vicinity of the proximal side of the outsole, the third section further including a plurality of groves which intersect said plurality of raised ribs in the vicinity of the distal side of the outsole, and the second section being smooth and being located between the first and third sections on the exterior face of the outsole;
• the interior face of the outsole including a cavity, said cavity including a plurality of protrusions extending across the interior face of the outsole within said cavity;
• a midsole having a proximal face, a distal face, a forefoot area and a hind foot area, the midsole having a first density in the forefoot area and a second density in the hind foot area, the midsole further having a first cavity located and positioned on its distal face and a second cavity located and positioned on its proximal face;
• an insole having a top face, a bottom face, a toe area, a midfoot area, a heel area, and an arch area, the top face of the insole including a plurality of raised projections forming a geometric pattern that starts in the vicinity of the midfoot area and fans outwardly towards both the toe area and the heel area, the plurality of raised projections increasing in size as they approach the toe and heel areas, the top face further including a series of U-shaped projections and a series of U-shaped groves located in the vicinity of the arch area of the insole;
• the first cavity of the midsole being shaped and dimensioned to receive the outsole and the second cavity of the midsole being shaped and dimensioned to receive the insole.

A three-layered shoe construction having a forefoot area, a midfoot area, a hind foot area, an arch area, a toe area, and a heel area, the shoe construction comprising:

• an outsole having an exterior face and an interior face, the exterior face including a first section located in the vicinity of the forefoot area, a second section located in the vicinity of the midfoot area, and a third section located in the vicinity of the hind foot area, each of said first and third sections including the plurality of raised ribs which form a first flexible area associated with each of said first and third sections, the first and third sections further including a plurality of groves which intersect said plurality of raised ribs forming a second flexible area associated with each of said first and third sections, the second flexible area associated with said first section being located in the vicinity of the proximal side of the forefoot area while the second flexible area associated with the third section being located in the vicinity of the distal side of the hind foot area, said second flexible area being more flexible than the first flexible area;
• the interior face of the outsole including a cavity having a plurality of protrusions positioned therewithin, at least some of the plurality of protrusions positioned and located in the forefoot area of the outsole being wave-like in shape and at least some of the protrusions located in the hind foot area of the outsole being straight in shape;
• a midsole having a proximal face and a distal face, the midsole having a first density in the forefoot area and a second density in the hind foot area wherein the second density is greater than the first density, the midsole further including a sidewall extending completely around the perimeter thereof, said sidewall including a raised projection extending around the perimeter thereof, said sidewall further including a first scored pattern located above the raised projection and a second scored pattern located below the raised projection, the midsole further including a first cavity positioned and located on its distal face and a second cavity positioned and located on its proximal face;
• and
• an insole having a top face and a bottom face, the top face of the insole including a plurality of raised projections forming a geometric pattern that starts in the vicinity of the midfoot area and spirals outwardly toward both the toe area and the heel area, the plurality of raised projections increase in size as they approach the heel and toe areas, the top face further including a series of U-shaped projections and a series of U-shaped groves positioned and located in the arch area, the series of U-shaped projections and groves having a center which is located and positioned in the vicinity of the center of the arch area, the series of U-shaped groves and projections being located closer to one another at the center as compared to other portions of the U-shaped groves and projections;
• the first cavity of the midsole being shaped and dimensioned to receive the outsole and the second cavity of the midsole being shaped and dimensioned to receive the insole.
