If the golden depiction of the Vlaamse Leeuw doesn't sell you, the fact that The Sock Guy SGX6 Gold Lion Socks are some of the most technically advanced cycling socks you can buy should. Sock Guy's SGX series of socks provide a compressive fit for optimal circulation, ribbed cuffs for comfort and breathability, and smart paneling for increased ventilation, reduced material movement, and less in foot friction. Made of a fancy blend of polypropylene, nylon, and spandex, they keep strong the Sock Guy tradition of reinforced heels and toes for durability, too. As cycling socks go, these are genius. Available with 6 inch cuffs in sizes SM and LXL. Made in the USA.
