My husband has diabetes, and has very little circulation in his feet, which are constantly “freezing”. We have tried so many things, with high hopes, only to be disappointed in their ability to keep his feet warm, especially now that it’s winter. I saw these and wanted to try them; he is thrilled!!! He said that the SECOND that he put them on, he felt warmth, for the first time in a LONG time! His feet don’t hurt when they’re warm, and I am so happy I tried these socks. The only problem (which we are going to solve shortly) is that they’re too thick to wear with his regular shoes, so he can only wear them when he comes in for the day; but we are going to buy him some shoes that are too big, giving him room to wear the socks everywhere. I highly recommend, ESPECIALLY FOR DIABETICS.
