All the same warmth as the original Heat Holders Crew sock, but in an extra long leg length - plus elasticated foot and ankle support. Works really well with boots and is great for spending time outdoors during the cold winter months. Thick, chunky, and with a massive tog rating of 2.34, these Mens Long Socks are made from a specially developed, heavy bulk yarn which has extreme thermal qualities. With long pile cushioning, these thermal socks will help keep feet fully comfortable and supported. The inside of each sock has been intensively brushed so that it not only feels sensationally soft, but also traps warm air close to the skin keeping your feet warmer for longer. Heat Holders are non-binding, are diabetic friendly, and provide relief for cold feet due to circulation problems.
