This is my 5th pair of Keens.  Like my other Keens, these shoes are very comfortable.  A nice plus with these shoes is that the back folds down so you can slip them on as mules.  I like the convenience of wearing them as mules if I have to run outside for a few minutes, but they're more comfortable with the back up.  I have to go up 1/2 a size for Keen sandals.  But, I ordered these shoes true to size & they fit perfectly.
