You can’t go wrong with the originals! No other socks can keep feet warm quite as well as Heat Holders, and that’s proven by their independent lab-tested TOG rating. Choose your perfect look from these women's’ SOCKSHOP Heat Holders 2.3 TOG Patterned Thermal Socks, in a whole range of colours and designs. The secret to Heat Holders’ superior thermal abilities is the advanced thermal yarn, specially developed in Japan, which is knitted up and given a unique, UK-patented long looped pile inside. That layer is intensely brushed, giving it a beautifully soft, deep fleece that can trap and hold on to the warm air in and around it, keeping it close to the skin through your day. You can ignore the cold, because Heat Holders keep you warmer for longer. Heat Holders in partnership with Scleroderma & Raynaud's UK. SRUK is the only UK Charity dedicated to improving the lives of people with Scleroderma and Raynaud's phenomenon.
