Abstract
A traction cleat for removable attachment to footwear includes a metal stud infrastructure with a vertical axis and two ends, the infrastructure further including a stem portion at the first end for attachment to a shoe, a head portion at the second end for tractive engagement with the ground, and a broad flange between the stem and head portions and extending radially outward from the vertical axis. A plastic skirt is molded directly upon the flange portion of the metal infrastructure, the resultant unitary skirt and flange forming the reinforced radial support member of the cleat.
