Made for use with closer-fitting snow sports boots that perhaps need a lighter, thinner sock layer, these men’s SOCKSHOP Heat Holders 1.0 TOG Slalom Adventure Ultra Lite Ski Socks provide the added warmth you want, and extra resilience too, with a specially reinforced heel for heavy sporting activity.

Despite the lighter, minimum thickness of these Ultra Lite socks, their thermal abilities are still in evidence, rating a 1.04 TOG, three times warmer than a basic cotton sock. This is due to the combination of Japanese-designed advanced heavy bulk thermal yarn, and an intensively brushed loop pile lining. This soft lining creates a network of fibres that capture and hold body-heated air for legs and feet that stay warm. Heat Holders are non-binding too, so diabetics, or anyone prone to cold limbs from circulation problems can stay warm too.
