Long hours, long distances, incessant impact: the distance runner and the triathlete know all about this. The RX300 retains the lightweight fit that many athletes prefer but with an added impact-absorbency cushion in the sole to help minimize the punishment on the feet when they repeatedly pound against the ground. We also included flat-knit mesh paneling, a full arch support, and TCK proDRI for insulation, moisture management, and protection against bacteria and odor.
