The present invention provides an article of footwear having an upper and a non-clogging sole attached to the upper. The sole includes a generally planar ground engaging surface and at least one traction member or cleat projecting from the generally planar ground engaging surface. The traction member or cleat is attached with a base surface adjacent the generally planar ground engaging surface, side surfaces projecting downwards, and a tip attached at a bottom end of the traction member. At least a portion of the base surface and the side surfaces of the traction member or cleat and at least a portion of the ground engaging surface of the sole includes an adhesion prevention material having both a low coefficient of friction and a low wettability with respect to water in a preferred embodiment. However, the tip of the traction member remains substantially free of the adhesion prevention material. The adhesion prevention material has a coefficient of friction of less than 0.4, preferably between 0.1 and 0.3, and the low wettability of the material is preferably characterized such that the average of the advancing and receding contact angles of a drop of pure distilled water on said adhesion prevention material (herein called the wettability index) is equal to or greater than about 90 degrees.
