Experience the same cosiness and warmth as the original Heat Holders thermal sock, but in a shorter ankle length. These sleep socks make a brilliant gift for any occasion. Choose from three individual styled tops: ribbed turn-over cuff, feather turn-over cuff, and feather edging. The feather turn-over cuff and feather top enhance comfort and warmth, while the ribbed turn-over cuff adds style for a more rugged look. Our advanced thermal yarn provides high-performance insulation against cold, with superior moisture-breathing abilities and softness. Innovative knitting technology creates a unique, short-looped cushion pile that traps more warm air, increasing warmth. An expert brushing process maximizes the amount of warm air held within each sock for unbelievable total warmth and all-day comfort. These are a 1-pair pack, available in 6 colours and styles, and come in sizes 4-8 UK / 37-42 EU / 5-9 US. They are made from a blend of acrylic, polyester, nylon, and elastane. Machine washable. These socks are scientifically tested to be 7x warmer than a basic cotton sock, with a tog rating of 2.3.
