They are over 7x warmer than regular cotton socks, and 3x warmer than ordinary thermal socks. They are better than heated, electric or battery operated socks because you can just put them on without fussing with batteries, wires etc.
Heat Holders® means no more cold feet! They are made using a unique 3-step process which makes them the warmest Thermal Socks. See the video so you can learn what makes them so warm and comfortable.
The invention came from a die-hard supporter of Manchester United, in Northern England.
One night, he bundled up to support his team from the stands, but did not survive the entire game as the cold crept to his toes, making his feet numb.
There had to be a solution... and there was!
A long time hosiery business veteran found the best yarn with high thermal properties as well as fantastic wicking capabilities. In the end, a cashmere-like acrylic yarn was developed. Soft to the touch, it promoted warmth and wicking.
A long loop thermal pile keeps the warmth close to the skin.
Air pockets within the sock are part of the technology. Warm air generated by the body is retained in these air pockets thus allowing the wearer to stay warmer for longer.
These elements of sock technology combined together gave birth to Heat Holders®
How do they feel?
First, you have to be aware of their thickness. If your shoes are pretty tight you may have a fitting problem.
Initially, you won't notice anything out of ordinary, just very fuzzy feeling, but vigorous activity like fast walking and especially running will give the user a feeling similar to putting his or her feet into warm or even hot water.
The effect of warmth is so profound that during intensive activity, it may be too much.
The author had experienced something related to walking on coal during fast running workouts last Fall.
If your feet are looking for an escape from the cold weather, Heat Holders® will be the answer!
