Very comfortable and very thick hem compared to other brands. It has this weird flap (as seen in the photo) on the fold. I'm not sure what it is. They don't rub or anything, but it's weird. I would say they are too thick for long distance running. It's doable for long distances, but I still prefer thinner socks. "Bow Support" doesn't go through my bow at all. (As seen in the photo) It's more of a gimmick anyway, so I don't care. I use them all day and find that they keep my feet from getting ripe and sweaty. If I don't have clean running socks I take them and they are fine as I like to walk long distances and sometimes jog more. If you prefer thicker socks, you'll probably like these. If not, then not! Even if you're worried about the aesthetics, this valve could be a deal breaker. π
