Familiarity: I've used it several times
I'm using these for tennis. They are comfortable and durable, and they breathe well. Probably because of the synthetics in the blend, they slide more easily in my shoe than the alpaca socks I used to wear but can't find now. So for tennis there is a bit of a stability problem, but they're still much, much better than cotton or all synthetic.
