Abstract:
A cleat attachment system for footwear, comprising:a cleat receptacle in a sole of the footwear, the receptacle having an opening and a cleat engaging structure including at least three equally spaced radial receptacle projections; anda rotationally attachable cleat having a vertical axis with first and second ends, including:at the first end, a ground engaging member; andat the second end, an attachment structure including at least three equally spaced radial cleat projections, each cleat projection:(i) being asymmetric with respect to an axis projecting radially outward from the center of the attachment structure through the radial center of the projection, and(ii) the radial center of the projection having a convex curved radial end;wherein the receptacle projections interact with the cleat projections so that less force is required to engage the cleat with the receptacle than to disengage the cleat from the receptacle.
