I've used several pairs (wear them daily) of these socks over the past couple of months. They are  very comfortable and provide good support. However, I gave it 4 stars only because I found out that they could also be purchased at Walgreens Drug Stores, thus avoiding Amazon's S&H. Other than that, and for the price, they are great! And, the most critical aspect, they retained their compression after numerous washings . . . of course, hang dry.
