Engineered for comfort and performance, the Pearl Izumi Men's ELITE Socks is loaded with features to help you PR your next bike race or triathlon. Made of a polyester, nylon, and Spandex blend, the material wicks moisture away from your feet while staying breathable, and mesh ventilation on the forefoot further improves air-flow. On the bottom of the sock is anatomic arch-compression to improve comfort and give it a performance fit. This mid-height sock is offered here with a pi core white color-scheme in size extra-large to fit Men's size 10+ and European sizes 44+. Pearl Izumi makes these socks in the USA.
