Best things I've bought. Very comfy & reasonable
My husband loves these as they help keep him warm in our cold house. However he has only had these for two months and they already have holes in (on the sole of the sock). I will still continue to buy these as they are so warm but the longevity of the socks isn't great.

The best from Heat holders as always warm, comfy and nonslip slipper socks, thank you.
I hate wearing anything like slippers indoors, but the colder months make this a challenge. Bought a couple of pairs of Heat Holders as my old equivalents had worn thin. I can't believe how good these feel on the feet. The inner material is soft and traps heat so well, but overall the socks are not overly thick so still allow my feet to breath and not sweat. I was pleasantly surprised by the understated styling. Not being a fan of novelty or "whacky" indoor footwear, these were perfect.
