Top notch socks for running-- I used them for a four mile jog and for a marathon. They fit snug not tight. I like the heel tab and they fit just over my running shoes so there's no rubbing at the line where some socks end just below the ankle and the shoes. Seem durable (but I have only had them a few weeks).
