Very good cozy socks, would recommend.
Heat Holder socks are perfect when outside, walking the dog or just being outdoors. I've had a couple of pairs for several years now and can confirm they wear well, wash well and definately keep you feet warm.
Should be called toasties holders definitely recommend them think I will buy more
Very warm and don’t fall down in my boots. Loose thread so I hope they will last a long time.
I have purchased at least a dozen pairs of these now. Because I wear them every day, they do wear out after a year or so, but the comfort and warmth these give me is great. I have poor circulation in my feet, so they're always cold and clammy, but these socks really help with the condition.
