About Heat Holders®

One winter’s day in 2006, while our inventor David Doughty was watching his son play soccer, he realized his so-called ‘thermal’ socks were doing absolutely nothing to keep his feet warm. Sock-makers had tried so hard to be cheap, they’d forgotten about quality. Right there and then, David decided to create a superior thermal sock. A sock so warm his feet wouldn’t know it was winter. Developing Heat Holders® took two years of hard work, dozens of experiments and a complete redesign of machinery. Eventually, we found the answer: a three-stage manufacturing process incorporating a high-quality acrylic yarn mix with an incredibly soft, cashmere-like feel, a special long looped pile and finally an intense brushing process. The key to insulation is to trap as much warm air as close to the skin as possible, and that’s what Heat Holders® do better than any other sock in the world. The Heat Holders® process was, and still is, absolutely unique. It gives our socks the best thermal properties available, with a tog rating of 2.34. That’s far warmer than heavy walking socks, nearly three times as warm as standard thermal socks and seven times warmer than basic cotton socks.Read their story
