The CW-X Compression Support Sock support your calf muscle, ankles, and arches with gradual compression to help your legs recover quickly after a long trek into the woods. A stretchy toe box eliminates that annoying feeling of your socks constricting your toes, and anatomically-correct left and right construction ensures the most dialed fit. And unlike your stifling cotton knee-highs, these socks rock mesh vents that allow heat to move away from the surface of your foot so your feet stay cool.
