A racewalking shoe must be extremely flexible as racewalkers roll through each step. A racewalker strikes with the heel, but it is a more gentle impact than that of a runner. A low, tapered and not overly cushioned heel is wanted. The shoe should be flat from heel to forefoot. The shoe should be lightweight for speed. It needs just enough cushion for long distance.
