I initially purchased these socks to use while visiting Disney World. They were great! They didn't slip down in my shoes and were comfortable even in 96 degree temperatures. I would definitely recommend these to a friend!
I fast walk three times a week for at least an hour each time. I originally bought these for exercise, but I find I wear them all the time. They are the comfiest sock I have ever owned. Snug, but not tight, stretchy, but maintain shape. They are soft and cozy. I now wear them around the house, too. I find myself putting on my sneakers just to go out to the store just because my socks are so comfy. Great socks.
