I purchased this shoe in the black and the "snapper" color in size 9. In Keens I usually wear an 8.5 - 9, my Keen sandals are 9's but my shoes and clogs are 8.5. I purchased the 9's due to other reviews of a similar shoe the ballet shoe that they were a hair to small. My KEEN Women's Kaci Clogs that i love are 8.5 and still quit tight even after wearing them awhile, just to give you an idea with what im abut to write. hese shoes feel good, however I have not had a chance to really walk in them, they do feel as though they could slip, a little wider around the heel I think. I would recommend these to a friend, but I would suggest ordering your usual size and a size above, with free returns when purchased through Amazon, why not!
