Abstract: A shoe construction including an outsole having a first section which includes portions of the forefoot and midfoot areas, a second section which includes portions of the forefoot, midfoot and hind foot areas, and a third section which includes portions of the midfoot and hind foot areas, the first and third sections including a plurality of curved and straight grooves and the second section including a plurality of diagonal grooves, the outsole further including a cavity, raised projections and a pair of protrusions for mating with a projected area and corresponding grooves and recesses on the midsole when the outsole and midsole are mated together, the midsole having a first density in the forefoot area and a second density in the hind foot area, the proximal face of the midsole including a second cavity for receiving the insole, the insole having a top face including a plurality of raised projections.

Abstract: A three-layered shoe construction having an outsole with a first section located in the arch portion and extending into and towards the medial side of both the forefoot and hind foot areas, and a second section located in the remainder of the outsole, the first section including a plurality of horizontal grooves, the second section including a plurality of small and elongated apertures, the outsole having a first cavity on its interior face; a dual-density midsole having a first density in the forefoot area and a second density in the hind foot area, the second density being greater than the first density, the midsole having a second cavity on its proximal face; and an insole having a top face including a plurality of raised projections, the outer perimeter and medial half of the arch portion being smooth. The specific construction associated with the three-layered shoe enhances flexibility, cushioning, and breathability.

Abstract: A three-layered shoe construction having an outsole with a first flexible area and a second flexible area located in the vicinity of both the forefoot area and the hind foot area, the second flexible area being more flexible than the first flexible area, and further including a cavity housing a plurality of protrusions therewithin; a dual density midsole having a first density in the forefoot area and a second density in the hind foot area, the second density being greater than the first density; and an insole having a top face which includes a plurality of raised projections forming a geometric pattern that starts in the vicinity of the midfoot area and spirals 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 specific construction associated with the outsole, midsole and insole enhance flexibility, cushioning, comfort and breathability.

Abstract: A three-layered shoe construction having an outsole with a first section located in the arch portion and extending into the proximal side of the forefoot and hind foot areas, and a second section located in the remainder of the outsole, the first section including a plurality of horizontal grooves, the second section including a plurality of small and elongated apertures, the outsole including first and second angled grooves extending across the outsole, the outsole having a first cavity on its interior face; a dual density midsole having a first density in the forefoot area and a second density in the hind foot area, the second density being greater than the first density, the midsole having a second cavity on its proximal face; and an insole having a top face including a plurality of raised projections. The specific construction associated with the three-layered shoe enhances flexibility, cushioning, and breathability.

Abstract: A three-layered shoe construction having a slotted outsole with two different types of oval shaped projections, one set of oval projections with channels and one set of oval projections with a non-skid texture, the oval projections with channels creating flow channels to guide liquid off the outer surface of the outsole and the oval projections with a non-skid texture providing traction; a dual density midsole having a first density in the forefoot area and a second density in the hind foot area, the second density being greater than the first density; and an insole having a plurality of apertures that extend from a terminal end of the toe area and cover the rest of the top face except for the arch portion, the toe and arch areas of the insole being substantially smooth. The specific construction associated with the outsole, midsole and insole enhance traction, flexibility, cushioning, comfort, and breathability.
