I ordered a 1/2 size up and the boot is still maybe a smidge too small with thick socks. Not really a snow boot because of its height. Those are the only two negatives-the pros way way out weigh the cons! The boot is super cute! Comfortable and since its a Sorel super warm-like what do they do to make their boots so warm? Magic! Im convinced! An added bonus, the boots make my feet look super small, I know I noted that they were a smidge too small? But only with say cabin socks-normal socks they are perfect! I love love love these boots and I bet you will too! PS they are so perfect for rain-and not like everyone elses duck boots!
