    I would like to say that these socks are absolutely wonderful. A week ago that is what I would have said. When they are working they are indeed wonderful. The heating element wrapped around the toes is exactly what my feet need and I was happy to have found these. However, the right sock has simply stopped heating. Doesn’t drain the battery at all, even though correctly connected. The sock itself is fairly warm (with no battery), but my right toes became icy and numb while the left toes were comfortable and warm. This is after around 15 uses - I’ve only had the socks for less than 6 weeks and the weather has mostly been mild. The socks are clearly under guarantee and now I have been trying to find how to contact the company to find out what to do. The links in their website do not work. (There is supposed to be a form to fill in, but the link only leads to advertisements.) There is no address for returns. There is no advice for non-functional socks. This is my second pair of Therm-ic socks. The first pair stopped working after one season of use. A short time, but I thought maybe I have not been careful enough. Now I have 3 out of 4 non-functional socks and no longer think this is my fault. I have been really careful with the new socks. Looks like a design fault. I am disappointed, but shall continue to try to find a contact with the company.
