text: Base member 24 and cleats 26 may be formed of nylon, rubber, or any other suitable material.
text: The cleat 34 is formed of rubber or of a synthetic resinous semi-rigid, resilient material which is rigid enough to maintain essentially its configuration under conditions of hard usage, which is sufficiently abrasion-resistant to keep it from being worn down unduly by repeated contact with the terrain on which it is intended to be used, but which is sufficiently elastic and resilient to enable it to be placed with the opening in its base over the end of the stud 33 and forced over the stud until the base of the cleat is in surface contact with the plate 26, as is illustrated especially in FIGURE 3.
