I found these boots to fit wide, which seems to contrast with most reviews here. I usually wear a 7.5 (average width), occasionally an 8, so I went with an 8 based on other reviewers' recommendations. The 8 was huge and I could pull the boot off even after tightening the laces as much as they could go. I exchanged for a 7.5, and it fits much better although still a touch wide. However, it feels well padded with a lot of  support so I am keeping them and I think they will work well for my needs (low-impact use).
