Abstract
A shoe sole has cushioning in ball and heel regions of the sole. The sole includes an insole which has openings in the ball and heel regions which increase the flexibility of the insole. The insole openings are filled in by a soft insole pad so that the insole does not form a barrier to cushioning the ball and heel of the foot. The outsole also has openings in ball and heel regions which are closed by clear covers. The openings provide for good flexibility of the outsole. A soft cushion is held in the cover for further cushioning of the ball and heel of the foot.
