Claims22
A composite cleat for an athletic shoe, said cleat comprising:
- a stud having a longitudinal axis for mounting the cleat to the athletic shoe;
- and
- a non-metal body comprising two non-metal components attached to said stud;
- wherein said non-metal body comprises a first component which substantially surrounds a second center component, the first component being formed of a disk of a first material having a first durometer mounted to said stud on a first major horizontal surface of said disk and the second center component being formed of a second material having a second durometer which is different than the durometer of the first material and extending from a second major horizontal surface of said disk,
- wherein said disk further comprises a plurality of vertical protrusions extending outwardly from said second center component to the circumference of said disk, said protrusions terminating in a longitudinal direction,
- further wherein either or both of said disk of a first material and said second center component contains abrasive particles.
