I really love World's Softest Socks. I am a senior woman and I started having foot problems several years ago. My feet sweat all the time all year long. It is very bad during the winter time. So I had purchased a couple of pairs of these socks several years ago, and I liked them so much, but I could not find them in the local department stores. I have been purchasing them on-line from Amazon., but I also purchase from World's Softest Socks website. The two places sell the same brand, but they are different. The ones from Amazon have a thinner more stretchy top and the foot section is thick, but not as thick as the others. But I still love the socks regardless of which style I get. I have about 20 pais now.
