These boots were a gift and I am so excited about them! They definitely run large (I usually wear a 9.5 or 10 in USA W, so I went with a 9 USA W - 6 AUS M). I can tell I need to break them in a bit, but they are wonderful and should be warm and sturdy for Midwest winters, hiking and just walking around every day. Also, Great Offer Stock delivered the boots in only 2 days, even though they estimated 3-8 business days. Very pleased!!
