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