Wow. I've worn these socks on a few 20-mile-plus mountain trail runs and they didn't bunch, and I didn't get as much as a chafe, which has never happened before. Frankly they were perfect.
Part of this due to the fact that they are made of CoolMax, which is excellent, but also the sock is a very fine weave and very soft inside.
I also like the fact that there's a different-colored trim on the top, which is more interesting than a plain color.
