Abstract: An assembly of a golf spike and receptacle assembly for mounting the spike are made to be joined in a nylon connection. This is provided by a receptacle assembly made of nylon and having a receptacle formed in a base portion and an arm extending radially from the base portion. Two forms of arms are provided, one having knobs and the other having an elongate aperture in which the knobs may be selectively received. The distance between receptacles may be varied by varying the position of the knobs in the aperture. A spike is provided having a metal spike member with a head, a flange and an anchor portion. The anchor portion is embedded in a nylon support member which forms a larger flange next to the metal flange and an engagement member having external threads for screwing into a receptacle. The anchor portion may have a circumferential groove, flattened edge, transverse or longitudinal grooves, a bore, or be partially hammered to produce an oval shape with outwardly diverging sides.

Abstract: An improved receptacle and spike assembly for athletic shoes is described. The spike assembly contains four fastening holes, and supports a spike and a connector. The improved receptacle is secured to a plate by embedding injectable material into cavities surrounding a suitable connector.

Abstract: A process and configuration for constructing the lower part of a spikeless type athletic shoe having molded studs on its undersurface to improve its wear-resistance is disclosed wherein portions of the sole and heel are premolded of an extra-durable material, such as high carbon content rubber, and then disposed partly cured in the shoe master mold at selected locations for molding and curing with the remainder of the sole and heel to produce a lower construction of conventional rubber molded with underface portions of extra-durability at the selected areas of greatest wear.
