Debra WeitznerMen's Thermal Socks - 4 Pair Insulated Heated Boot Socks for Extreme Temperatures

Game changer. Have tried many socks spanning years to keep my feet warm when I sleep and these by far have been the best. I am allergic to wool so I have to find other materials. As a senior citizen (over 70) am starting to have arthritic and other age related issues and cold feet start to ache and wake me up. These socks are extremely comfortable and non-binding. They are not bulky and wash well. I do not wear them during the day only to sleep so hopefully they will not wear out and get holes too soon.

It's 100% made with acrylic and are really tick (1 cm tick ). It's hot in winter and comfortable in the boots. It's feel like to be on a tick carpet.

These socks are warm, soft and not bulky. They fit inside our outdoor (LL Bean) boots and sheepskin slippers. Great to wear around the house by themselves on carpeted floors. (They don't have "traction dots").

I bought these socks for a coworker who is always complaining her feet are never warm. In fact, the day they arrived she was complaining about how cold she was when I walked into her office. She wasn't sure about changing her socks at work, but did it anyway. An hour later, I passed her in the hallway and she commented it was the first time in ages her feet were actually warm. She said, "My feet are so warm, my toes are even sweating. I think I am going to wear these every day. Thank you!"

Good socks, but feels cheated, cos it is 2 pairs, 4 socks, not 4 pairs. Anyway...Keeping it, cos too lazy to return, but will get cheaper alternatives. S$15 per pair of socks is pretty expensive.
