The mostly great reviews convinced me to try these.  I got an awesome pair of aqua chucks I wanted to wear with cuffed jeans/capris, and not have socks hanging out.  These fit the bill, except they didn't. Just 10mins of walking and the sock had totally slipped of my heel and is balled up under my foot. After repeated attempts to fix them I gave up.  Such a bummer, I've yet to own no show socks that work for me. These are quite thin as well.
