Slay singletrack with pride in your Sock Guy SGX6 IMBA socks. Sock Guy gave the IMBA sock a cool, retro IMBA logo to let the world know that you support dirt lovers everywhere. But it makes us wonder if it's retro, wouldn't it be NORBA' The Sock Guy SGX6 IMBA 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.
