SmartWool PhD RULMS Rock!
Blended composition? Fabric drawbacks? Nylon components? 4Degree Elite Fit system? ReliaWool technology? I've never really thought about the value or my enjoyment of all those features, but I do really like these socks. As with all SmartWool products, I'm surprised I'm willing to pay this much, but I do keep coming back for more!
Pic below, taken at cemetery where I run, shows how much sock is visible above shoe.
