Performance Twelve Sock

You don't have to be nursing an injury to benefit from compression — whether you're tapering before your 70.3 next week or riding through a hard interval set, you could benefit from the Managed Compression in Swiftwick's Twelve Performance socks.

Rising above the calf with a reinforced twelve-inch cuff, the socks' bodies are constructed with Olefin in a high needle knit while the wear-prone toe and heel areas receive durable T-66 nylon. Both fibers are adept at pulling moisture away from your feet quickly as you ride, and graduated compression through the sock stabilizes muscles and encourages circulation to promote recovery from your hardworking calves to the tiny, underappreciated tendons and ligaments of the foot.

Best Socks

I've put it through the wringer

Swiftwick always makes the BEST socks and they last forever!


Are these as slick/smooth as the photo shows? They seem to be just what I am looking for. I dont like bulky or heavy ribbed socks.
