A compression force of a foot landing on the horizontal sole portion causes an increase in fluid pressure in the foot portion which stiffens the vertical foot portion forming a bumper-like wall for absorbing side impacting force from the foot and serving to keep the foot on the footbed. The stability device can include a plurality of finger-shaped elements.

Abstract: A golf shoe is provided which facilitates a stable swing by causing a golfer to pull his knees inward securely. Because of the inwardly pulled knees, a gap is inevitably formed between the outer edge of fore shoe and ground surface. This gap usually causes unnecessary body movement during swing, and eventually leads to a loss of swing strength and accuracy (this is referred to as a sway). In order to prevent the sway by avoiding formation of the gap, a special golf shoe sole is invented. When a golfer is taking a stance with his knees pulled inward the inner part of the fore sole is lowered and the outer part of the fore sole is raised. Technical function of the sole is achieved by installing the inner (1) and outer (2) fluid chambers which are interconnected by the solution moving velocity control path (3). During swing, the slope at the fore part of the sole is adjusted optimally by itself by the pressure distribution of foot.
