These socks may be expensive, but they are worth it. In Africa I used these socks more than any. Full day hikes in the rain, and my feet were still extremely warm, dry, and comfortable. In the walks in the heat, these socks kept my feet cool, dry, and also comfortable. As a bonus, they don't seem to get smelly like my standard cotton socks. I was able to wear them multiple days without washing at times when there were no washing facilities available.

Now I use them any time I will be dining any hiking, or even taking long walks in the park. If they were a little less expensive, I wouldn't purchase any other sock.
