Anyone who is out in the cold, for work or for sport, will love these Terramar Battery Socks. A simple 9-Volt battery operates the internal heating system, keeping your feet cozy no matter what the weather.
I thought they could be the answer to cold feet. The socks them selves are warm but the heated part doesn't work at all. I didn't notice the difference from them having the batteries in them for an hour to just having the socks on for an hour with no battery!
Sorry to report these socks did not keep any feet warm on the first use. I purchased three pairs for the fellows hunting trip. Huge disappointment for my husband and sons! I will be returning the socks for a refund but I wasted money on batteries.
