ROTATING CLEAT ASSEMBLIES FOR ATHLETIC SHOES

摘要

A shoe (30) having a selectively rotating cleat assembly (42) mounted to the sole (34) of the shoe (30) below the ball of a wearer's foot. The rotating cleat assembly (42) includes a core that mates with and is held in rotatable engagement by a recess (46) in the sole (34) of the shoe (30). The rotating cleat assembly (42) is free to rotate relative to the sole (34) when the force of impact with a playing surface is substantially normal to a central rotation axis (48) of the cleat assembly (42). The rotating cleat assembly (42) locks relative to the sole (34) of the shoe (30) when the force of impact with a playing surface is a predetermined angle from the central rotation axis (48) for a given force.
