I have no idea why people keep saying that you need to order a size up – now that I (a size 13us mens) have ordered a size 14us mens pair I can say for certain that if you order a size up it is ridiculous. YES a BRAND NEW size 14 does fit my size 13 foot snugly when I first put them on, but I wasn't born yesterday, and I can easily tell that they will loosen up allot if I wear them for a while. When put a little pressure with my foot to compress the very thick, lush fur forward so my toes reach a normal, comfortable distance from the toe of the shoe, I have around an inch of space in the heel. This is a brand new, leather shoe, with fur lining – leather stretches, and fur compresses over time, that is the nature of those materials.<br /><br />In my opinion, when UGG manufactured these shoes they made them exactly the right size so you do not need to order a size up. I can understand why someone who wears a 7, or 8, or 9, or MAYBE even a 10, MAY, possibly want to order a size up, BUT if you're an 11 or above I would strongly discourage it.<br /><br />I rated the shoe with 4 stars because they are great quality construction and good materials. It is not UGG or the sellers fault if I ordered a size up based on bad advice and, oddly, the size up fitted as a size up should fit: loose.
