The FXR Riding Socks Air are engineered to keep your feet cool and comfortable through long days in the saddle. A lightweight acrylic and nylon foot with reinforced toe and heel provides lasting durability, while the polyester and spandex upper wicks moisture and incorporates a ventilated knit panel to maximize airflow. The extra-long design is ideal for use with knee braces, and silicone security strips on the inner and outer elastic help keep the socks securely in place. Ribbed arch and ankle support complete a performance-driven design that delivers comfort from the first mile to the last.
