A shoe for running, cross training and the like includes a base member including a raised front portion and a rearwardly extending rear portion. A U-shaped spring is disposed beneath the raised portion. The spring has transversely extending ends engaging the front portion at respective longitudinally spaced locations. The front end of the spring is preferably unconnected to the raised portion such that a projection on the latter cams against and flattens the spring when the user's weight is put on the raised portion. A sole spring element is affixed to the front portion of base member and includes a flexible part overlying, and extending rearwardly beyond, the sole portion of the base member. The flexible part of the rear spring element is disposed at an acute, non-zero angle with respect to the sole portion of the base member.
