Though I now live in Los Angeles, I lived for many years in Minnesota so I know how important it can be to keep your feet warm. For several years now I have had a problem with cold feet due to a condition known as peripheral neuropathy. I have purchased many different types of socks to help my feet keep warm. These are the best I have found. Though not as soft as merino wool these are definitely warmer and more durable. They are well made and will last a long time. I would and will purchase them again and recommend them to my friends.
