I bought 3 pairs of these socks for my family and one for a friend. They sit out in the cold and hunt. They are great, BUT on a brand new 9 volt Duracell battery, they lasted about 3 hours. So they definitely work, but make sure you have extra batteries with you. Oh and the heat is on one side of the sock, but they said their feet still stayed warm :-)
These socks are great. My doctor recommended a sock with some compression. These aren't actually compression sock, but he thought they had enough compression to suit my purposes. I would definitely recommend these socks and I would buy them again.
These socks are nice and thick and comfortable. The toe is smooth and comfortable and the tops stay up without being too tight. I am a woman who wears a size 11 which is about a size 9 1/2 in mens shoes. These socks are just right for me so I cannot imagine them stretching out to fit a size 12 1/2 in mens size. Keep this in mind when ordering.
