The new Heat Holders ladies Lite Thermal Socks are finally here! Designed for ultimate comfort and warmth, these socks are not as chunky as the original Heat Holders, allowing them to fit easily into normal dress shoes or trainers. With a TOG rating of 1.6, they provide excellent insulation against the cold while still offering superior moisture-wicking capabilities. The innovative knitting technology creates extra-long looped cushion piles to trap more warm air, increasing the TOG rating for all-day warmth. Expertly brushed to maximize the amount of warm air held within each sock, these thermal socks are scientifically tested to be 5x warmer than basic cotton socks. Available in various stylish marl twist patterns, your feet will be both elegant and warm. These crew-length socks are made from a blend of 93% Acrylic, 6% Polyester, and 1% Elastane. They are machine washable at 40°C and can be tumble dried, though line drying is recommended for best results. Size: UK 4-8, EUR 37-42, US 5-9.
