All the same warmth as the original Heat Holders® Crew sock, but in an extra long leg length, plus elasticated foot & ankle support. Works really well with boots and great for spending time outdoors during the cold winter months. Keep feet warm on the coldest of days and pull on these ribbed, cuffed, Heat Holders® for women, the warmest thermal sock yet. The inside of each sock has been intensively brushed such that they not only feel sensationally soft but also trap warm air close to the skin keeping your feet warmer for longer. Heat Holders® are non-binding; they are also diabetic friendly, and provide relief for cold feet due to circulation problems.
