I *love* Keen shoes and have more pairs than I care to admit to my husband.  All of them are the same size, and all of them fit perfectly and are the most comfortable shoes for my feet.  I purchased these Paradise sandals to replace the first Keens I bought years ago, which were a similar sandal but the strap broke.  When I took these new sandals out of the box I was struck by how small they looked.  This was not an illusion, for when I tried them on they were small; my heel just popped over the back of the sole.  I held them up to my old pair and the new ones are almost an inch shorter.  Thanks to Amazon's great return policy, these will be going back.  But now I am unsure if this was an anomaly, or if Keen's sizing has changed.  All of my other Keens still fit!

For the brief moment I had them on they were quite comfortable and had the sizing been right, I am certain these would have been my shoe for the summer.
