Ordered these for my husband. He's a size 9 in shoes so thats what I ordered and the fit was perfect. I found the boots to be a little heavy and I was looking for a lighter boot so I was disappointed with the weight of them. It's been a very mild winter here in NJ so far this year so can't speak of durability or warmth. However, they do seem very well made so I'm not too worried. Again, I had ordered these because some of the reviews said they were not heavy but I disagree and think they have a lot of weight to them. Should have bought a pair of North Face because they are very light, durable, and easy to wear.
