I read many reviews about this shoe before buying them. I'm pretty much a true 8.5 yet when reading the reviews went to a 9. They will do fine as long as they don't stretch too much. I would have probably been ok with an 8 as there is more room in the front than I like as I like to be closer to the front, but not over the front! The strap where the buckle is is very thin which at the price to me was a bit of a let down. I've not worn them outside yet as I'm still in colder weather where I live.
