Revised. I have used Grip 6 socks daily for a year working in a hospital, and have found them comfortable, long-lasting, and a good value. I experienced minimal wear except for a few small holes near my toes (from my toenails). My husband and I both recently purchased new Grip 6 socks. We still like the quality and cushioning, but my husband says he didn't like that his shrank a lot in the dryer (which we know is not advised). He says they are too hot in the summer (outside in NC), too tight, and always too short in length up the calf to be comfortable in work boots.
