An athletic shoe has a sole composed of an inner layer and an outer layer that comes into contact with the ground surface. In the athletic shoe, a plurality of downward projecting projections are formed on the lower surface of the outer layer as parts of the outer layer, and a ring-shaped flange portion is formed as a part of the outer layer to surround the corresponding projection. The ring-shaped flange portion slants upward from its outer edge toward the inner edge. When a downward pressure greater than a predetermined value acts onto a portion where the projection and the corresponding flange portion are formed, the flange deforms in order to move the projection downward. In another athletic shoe, a plurality of projections is formed on the outer surface of a sole, and a depression is formed in the outer surface of the sole in the vicinity of each of the projections. The athletic shoe is excellent in terms of performance in gripping a soft ground surface such as a lawn surface and the easiness of walking on hard surfaces such as a paved path or a floor.

A method for forming a unitary polymeric projection or fastener comprising a thin, strong flexible backing, and a multiplicity of thin spaced hook members projecting from the upper surface of the unitary backing the method generally including extruding a thermoplastic resin through a die plate which die plate is shaped to form a base layer and spaced ridges, ribs or hook elements projecting above a surface of the base layer. When the die forms the spaced ridges or ribs the cross sectional shape of the hook members are formed by the die plate while the initial hook member thickness is formed by transversely cutting the ridges at spaced locations along their lengths to form discrete cut portions of the ridges. Subsequently longitudinal stretching of the backing layer (in the direction of the ridges on the machine direction) separates these cut portions of the ridges, which cut portion then form spaced apart hook members. The extruded hook members or cut rib hook members are then heat treated resulting in shrinkage of at least a portion of at least the hook head portion thickness by from 5 to 90 percent, preferably 30 to 90 percent.
