I've had a pair of the classic green Crocs since 2007 and I wear them around the house. After developing a heel tendon problem, I wanted something  comfortable to wear at work as well, but wouldn't scream Crocs. These fit the bill perfectly and I love wearing them--so comfortable. I usually wear a size 8 with socks (not the thin dress socks variety) and the fit is good, slightly roomy. I love the cushiony feel.
