The harder your feet work, the more likely they are to fall victim to blisters and general friction-related problems. Bridgedale Coolmax Liners help combat soreness and even allergies by putting a fine-knit barrier of soft and moisture-wicking Coolmax microfibres between you and your outer socks. Bridgedale Coolmax Liners act as a non-slip layer for the skin to stop blisters, while also helping against sweat rashes and other allergic reactions by delivering extra comfort and dryness.
