The extra-high design is specifically crafted to be worn over knee braces for added comfort and protection during motocross activities. Made from a thin, lightweight polyester/spandex blend, these socks ensure your feet remain cool and dry. A large mesh element on the back significantly improves ventilation and airflow, enhancing breathability. The foot section is composed of 57% acrylic, 24% nylon, and 19% polyester, while the leg section is made from 100% polyester. These materials collectively offer durability, flexibility, and optimal moisture management, making these socks a perfect companion for rigorous off-road adventures.
