Abstract: An athletic shoe includes impact sensing means disposed in contact with the impact cushioning material disposed between the inner sole and the outer sole of the shoe. The impact sensing means comprises a rupturable material having encapsulated dye. If the impact pressure effective upon the medium exceeds a predetermined value, the medium ruptures, releasing the dye for providing a visual indication that the impact pressure exceeded a predetermined value. A plurality of strips of rupturable material can be provided, each rupturing at a different pressure and each having dye of a respectively different color.
