"these are super cute, and very comfy! perfect for cool fall nights and winter pizazz. i am in between a 7 1/2 and an 8, so i bought an 8 to be safe. its a little big so i will say they run true to size. if you want a bit of room, (given you have average width feet) order a half size up, if you want a perfect snug fit, go with your true size."
