Tested by top trail runners and outdoor athletes, the full length MudGear Premium Long Compression Socks were over engineered to be tough and prevent nasty gashes caused by rope traverses and painful slides across other obstacles during Obstacle Race competition. This is the only compression sock built with a layer of padding on the lower leg and calf designed to protect from rope burn and other injuries. While the durability of this sock was originally developed for OCR, the quality American construction makes this sock great for any situation which requires an extra layer of comfort and durability. The difference comes from 168 needlepoint compression construction and tougher yarn which provides ideal compression and superior abrasion resistance, when compared to other gym quality compression socks and sleeves. While these socks are extremely tough and durable their designed to drain quickly and remain light-weight for long distance OCR courses, mountain bike rides, or hikes. Our long-lasting construction make these socks perfect athletes of all types including, Motocross, Field Hockey, Ice Hockey, Soccer, Football, and many more. These socks are also great for anyone who spends a lot of time on their feet, like nurses, police, firefighters, construction workers etc. The 15-20 mmhg graduated compression helps to alleviate symptoms of various medical conditions.
