Swiftwick Performance Twelve

The 2016 Swiftwick Performance Twelve is a compression sock. Starting with the Performance foot, the Twelve adds a four-inch double cuff and sturdy welt landing above the calf for decided increase in circulation, reduced recovery time and lowered lactic acid buildup. Construction is impeccable; the seams are smooth, stitching is very durable, and the body is breathable, keeping feet cool and dry. Reinforced at heel and toe to absorb impacts.
A very good compression sock.
