Like others have posted, these shoes are sized much too large so I had to size down to smaller size. But that is not my main gripe. I've had these shoes for about a month now which isn't a long time. So far, they've worked out quite well for casual hot days. Unfortunately when I went to put them on today, I noticed that there was a small hole in one where my big toe is. I assume most folks will wear these things without socks like me so it was shocking to see that the mesh material used didn't last longer than a month. The shoes I have are not tight either and have a loose fit (I went down 1/2 size). And I keep my toe nails trimmed. I'll be returning these and may exchange to see if the ones I had were just defective. But I would hope that Olukai considers more reinforced material in the toe-box area for future versions of this shoe as they are super comfy and I really do like wearing them.
