These ended up being a little big for me, but I find them very comfortable, which a nicely padded insole and a hard sole that allows me to run out to get the paper or take the dog out while I'm wearing them. Warm enough for cool mornings/evenings, but not super-hot. Washable and it appear that they'll be pretty durable as well. This is my second pair of Acorn slippers, and I'm definitely a fan.
