Blistering is a thing of the past with Hilly's ever-popular Twin Skin sock. A dual-layer sock ensures material does not rub against the foot, eliminating the key cause of blistering. The inner layer is designed to wick sweat effectively away from the foot, keeping it dry. An elastic band around the midfoot provides support to the arch, and with all seams on the outside of the sock blistering really is eliminated!

This is a brilliant sock for something like the Wildcoast Wildrun, or big mountain run-ing in Winter.  The sock is hot as a result of its double layer, so if you are looking for a summer sock or one not so hot go for the Hilly Mono Skin.
