Patent ID: 7370444

Claim:
A cleat receptacle comprising: a. a cleat-engaging structure, the structure characterized by an axis about which cleats are rotated for insertion into or removal from the receptacle; and b. a shoe attachment structure surrounding the cleat-engaging structure, the shoe attachment structure including a flange for attachment to an outsole of the shoe, the flange including an edge surface, the edge surface a surface of the flange such that the normal to the edge surface is substantially perpendicular to the cleat engaging structure axis, the flange further including at least one paddle projection attached at a paddle projection edge to the edge surface such that the degree of tilt of the paddle projection is in the range from approximately 20 degrees to 70 degrees, where the degree of tilt of the paddle projection is the measure of the angle that the normal to the broadest face of the paddle projection makes to a measurement plane and where the measurement plane is a plane that contains the cleat-engaging structure axis and a line perpendicular to the cleat-engaging structure axis such that the line contains the centroid of the broadest face of the paddle projection.
