An athletic shoe construction having shock absorbing elements in the heel and forefoot areas of the sole portion of the shoe which elements are surrounded on their sides by comparatively hard rim portions of a sole shell or mid-sole.
Claims2
In an athletic shoe construction having a sole portion connected to an upper portion and where said sole portion includes a heel area, an arch area, a forefoot area and a toe area;
- the improvement comprising in that said sole portion includes an outer sole, a heel wedge having a cutout therein and a mid-sole overlying said forefoot area and having a cutout therein;
- in that the cutout in the heel wedge has a first shock absorbing element therein, in that the cutout in the mid-sole has a second shock absorbing element therein, in that the remainder of said sole portion including said toe and arch areas comprises a harder material than said first and second shock absorbing elements, and in that the outer peripheries of both said elements are surrounded by said harder material to provide stability and support to a foot when side thrust loads are imparted to the shoe.
In an athletic shoe construction having a molded sole shell connected to an upper portion where said molded shell includes a heel area, in arch area, a forefoot area and a toe area;
- the improvement comprising in that said molded sole shell includes a recess in the forefoot area and a recess in the heel area with the portions of the sole shell between the side edges thereof and the recesses forming support surfaces to provide stability and support to the foot when side thrust loads are imparted to the shoe, in that a first shock absorbing element comprising a softer material than said molded sole shell is included in the recess in the heel area and that a second shock absorbing element comprising a softer material than said molded sole shell is included in the recess in the forefoot area, and in that the portion of the molded sole shell extending between the front thereof and the recess in the forefoot area forms a support surface against which the toes of the foot may bear to provide a propulsive force during jumping.
