SockGuy Double Knit Mesh in 6" crew cuff with stretch-to-fit sizing. Sometimes, during hot summer rides, your feet feel like they've been dipped in hot sauce. Not so, ironically, when you're wearing Sock Guy SGX6 Sriracha Socks. The Sock Guy SGX6 Sriracha 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.
