I've gone through a lot of socks in my six-plus decades, and if I could only buy Thorlo from here until my dirt nap, I'll be a happy man. They're snug and supportive, and the cushioning in the heel and ball is effective without adding too much bulk. In my experience with other Thorlo styles, they've endured considerable use & abuse before wearing out, and I expect these will do as well. My only gripe is that I wish there was a definitive guide to the features of each style.
