Some athletes are more prone to hot spots than others; and when the distance is great and the hours of training long, minor hot spots can quickly turn into painful debilitating blisters. Such a scenario has often brought an important training regimen to a screeching halt or seriously hampered one's ability to place. As with lots of sporting injuries, preventative maintenance is key, and that's where our RX500 comes into play. Hot spots form when friction and moisture combine to irritate the skin, so this sock is big on friction reduction, breathability, moisture-wicking, and comfort. A cushioned sole and a terry top boast Coolmax^®, with its well-known ability to transfer moisture and heat away from the skin, while Mohair fibers knit into the heel and toe minimize friction and help the blister-prone areas to stay dry, comfortable, and free from chafing. The middleweight nature of this sock also insulates from both heat and cold. If a propensity for hot spots holds you back, then let the RX500 be your first-aid field kit.
