Abstract: A shoe including a sole and an upper. The upper is coupled to the sole. The upper includes an outer layer and an inner layer. The outer layer has an outer surface and an inner surface. The inner surface of the outer layer is in direct contact with the inner layer. The outer layer is a hot melt thermoplastic material, and the inner layer is a material different from that of the outer layer. At least a portion of the outer layer is adhered to the inner layer, and the inner layer including a portion not covered by the outer layer.

Abstract: A shoe comprising a sole and an upper secured to the sole. The sole has a sole bottom surface, a plurality of first lugs projecting generally downwardly from the sole bottom surface, and a plurality of second lugs projecting generally downwardly from the sole bottom surface. Each lug of the first plurality of lugs has a distal end surface facing a first direction which is oblique relative to the longitudinal axis of such each first lug. Each lug of the second plurality of lugs has a distal end surface facing a second direction which is oblique relative to the longitudinal axis of such each second lug, and wherein the second direction is different than the first direction.

Abstract: A shoe having a sole. The sole includes a midsole including multiple midsole portions. A first midsole portion is an inner portion of a first midsole material. A second, midsole portion of a second midsole material circumscribes the first midsole portion, and a third midsole portion formed of a third midsole material circumscribes the second midsole portion. The second midsole portion has a greater durometer hardness than the first midsole portion. The third midsole portion has a different durometer hardness than the second midsole portion. The second midsole portion is of a different color than each of the first midsole portion and the third midsole portion. An outsole secured to the midsole is sufficiently translucent so that the first, second, and third midsole portions are visually discernable one from another by a person of normal, unaided vision viewing the outsole.
