I wish I found these years ago as they would have helped coping with the NY/NJ winters that I grew up with.  They are expensive compared to other socks although there is a huge difference in quality.  When I put these on, I feel like I am wearing a wool slipper.  When I put on my boots with these socks, my feet stay nice and warm during the cold.  I would highly recommend this to anyone living in an area that receives snow.  If you are living in Florida or Puerto Rico, then perhaps these socks might be a bit much.
