The RX900 Fluorescent boasts our highest level of Oxysox® Compression Technology in a hot fresh color option. However, for athletes who know the punishment of incessant impact and find themselves prone to hot spots and blisters, we’ve tacked on some extras–a high-density impact-absorbency cushion in the sole and a high-splice for added protection against abrasion, hot spots, and blisters. Thus, you get the best a graduated compression sock has to offer (maximum performance-enhancing mmHg ratings, ultra-lightweight support, and durability for the long haul) plus a dose of preventative maintenance to help you comfortably compete, train, or recover.
