I have Reynaud's Syndrome (it "goes with" my rheumatoid arthritis) and my hands and feet are constantly painful and miserably cold. I discovered keeping my feet warm reduces the pain considerably. My husband got these socks for me, and I wear them over a thin pair of socks for a layering effect. It really works! I can only think they would be great hiking socks - even in severely cold weather.
I highly recommend them. And I'm grateful that I have a caring husband that gets things like this for me to make me feel better!
