Breathable Work Socks

The Portwest SK18 Socks have natural moisture wicking abilities, which ensure the socks can breathe and move moisture away from your feet toward the surface of the sock. This movement allows moisture to evaporate quickly instead of keeping it near your feet, causing sweat and odours.
