"Love these socks! Toes are comfy and warm!"
"Love their socks. Super soft & toasty warm!"
"I have Chilblains and I struggle to find the right socks. They need to be warm but not too warm and no irritating seams on the toes. These are perfect. I've tried heated socks, toe warmers (both chemical and physical), socks where the toes are separated, etc. Nothing works as well and these socks. They should market them for Chilblains but I'm sure it's not that simple. If you suffer from Chilblains (and I've heard Raynaud's is similar) I would definitely give them a try."
"These socks are wonderful! They do not irritate my very sensitive skin, and they are comfortable and lush feeling. They have protected my feet very well in this winter's awful weather. My new favorite thing!!"
"GREAT FIT , wash and dry without any problems , super comfy and warm ! I wear them with boots & sneakers."
"This was my first time ordering Heat Holders. I was looking for a sock to wear under my sneakers for winter walking. Heat Holders are warmer than I thought they would be and are keeping my feet warmer than wool socks have in the best. I am so happy to be walking with warm feet again. Happy Winter!"
"Keeps my hiking feet warm even in Northern Michigan."
"Warm. Comfortable. I have bought more for myself and friends"
"Warm cozy comfortable with a great fit"
