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.
