I ordered my typical size 8 in these shoes, they ended uo being too small when I tried them on. Despite that, I really liked the look of them and will purchase the 8.5 after my return is completed. As always, the Amazon return process was painless (part of the reason for the 5 stars). I have a similar pair of Merrells that are very comfortable, I practically lived in them last summer. I think the bigger size will work out well and be another live in shoe this spring/summer. If you like the barefoot/minimalist shoes, youll be happy with these but maybe go up half a size from your normal.
