Les chaussettes sont tout simplement une merveille.La froid a fait ses valises et s'en est allé.La douce chaleur se diffuse comme une brise poétique.J'adore! Merci
The reason l buy heatholder socks is they keep my legs from my knees down warm. When l was 5 yrs old l had polio and from 1971 to 2005 l had 6 operations on my knees with complete removal and rebuilds on both. In 2006 l was told l was a diabetic due to 30 years of shift work !!! .This why l buy these socks. I am 73 now and will do till l die.
The warmest I've had
I have quite a lot of Heat Holder socks in a variety of styles and, though I am a woman, usually wear the men’s version of these because they are more spacious and can be pulled up higher. Though these boot socks are good, I was a little disappointed to find that the top section of the leg is NOT brushed and fluffy inside so the full warmth of the sock doesn’t extend right up to my knee. I think you can see from what I’ve said that I don’t turn the top of the sock down but make it extend as far up my leg as possible. I have a male friend who does the same with his Heat Holder boot socks and also wants the whole of his lower leg to be warm. I wish Heat Holders made a sock that was 2.3 tog all the way up to the knee.
