Designed for the athlete in mind, The TR-1 insole provides cushioning from shock when running, jumping, or engaging in physical activity. It is made of a rubber-foam composite that absorbs shock while providing support when pressure is applied. In the past, insoles were made of flat strips of leather. These types of insoles eventually would flex and contour to the shape of the wearer's feet but didn't provide much in the area of cushioning.
