I have been wearing keens for years and this type of keen the most. I usually order a size 9 in this type of keen and did so with this model as well. Although this model is a bit shorter than my last pair, the toe box is a bit wider so they fit fine and feel as comfortable as my others have. I am on my feet a lot via my job in academia but I am also a triathlete so run a lot and usually before work so my work shoes need to be comfortable. These do the job so far.
