text: In order to ensure that the mechanism of engagement and release of the cleat assembly to the pedal assembly occurs smoothly and without significant disruption, at least one of the two sets of contacting surfaces, the first of which comprise the first urging surface 314 and the outer surface 280 b, and the second one of which comprise the cleat assembly's shaped insert 320 and the edge surface 282 b of the rearward cleat retainer 280 b, are preferably made of a material having sufficient strength to withstand the repeated application of force and a sufficiently low coefficient of friction to permit the smooth relative sliding of the contact surfaces.
