Blisters start where skin rubs against the boot.
A paper published by the US military named a double-layer sock, with an inner structure that protects the skin from rubbing, as the ideal sock for combat boots. Taking our cue from that, we proposed a double-layer walking sock to a UK outdoor retailer.
Two layers take the rub. The inner layer moves with the foot and the outer layer moves with the boot, so the friction happens between the layers instead of on the skin.
COOLMAX® for wicking. COOLMAX® yarn pulls sweat away and dries fast.
