In a range of colours and patterns, designed as a medium thick, mid-weight sock for casual shoes and boots, when regular Heat Holders socks are just too chunky for your footwear, then these Heat Holders 1.6 TOG Lite Patterned and Striped Socks will fit the bill... and in your shoes! They’re made from the same thermally efficient, Japanese-designed yarn as the full thickness socks, but with less dense bulk and shorter loops to the pile lining. The looped pile of every sock is then intensively brushed, giving the surface not only superb softness, but a bed of fleece fibres that can trap more warm air, holding it in those fibres and close to the skin, which allows the socks to keep your feet warmer for longer, proven to be more than 4x the warmth of a basic cotton sock. For your even closer-fitting shoes, perhaps try our minimum thickness SOCKSHOP Heat Holders 1.0 TOG Ultra Lite Plain Socks. 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.
