I was ready to send these back for being a bit loose, and not my typical style, but after wearing for awhile they are one of my favorite pairs of shoes.  They run a tad large.  I'm a 5 in Keen, 5.5-6 in other shoes but these are a tad loose.  Since they have the strap they fit secure and very comfortable.  My one requirement with shoes is that I need to be able to run in them if needed.  These fit that requirement.  They aren't a hiking shoe, but are great for urban walking.
