Because of other feedback, I ordered a size up (normally a 6-6.5, ordered a 7). It's very loose in the heel, and a little loose throughout the foot. With a pair of hand-knit socks and legwarmers, though, I anticipate them to be a little more snug. The knit end doesn't come down as far as the photo, but as others said, I'm thinking the knit will stretch out a little bit. Might keep the packaging cardboard to try to wrap around the shaft underneath the knit to help keep it's shape. They don't seem like they'll be the warmest, but like I said, I like multiple layers underneath! They're very cute, and a good alternative (price-wise) to the Uggs I've been coveting for years. Soles are stiff and flat and feel a little cheap. Like really thick foam. Probably shouldn't get them too wet.
