I based the size I ordered on other Keen sandals I have, so I don't know what happened here...there's a full 2" between the tip of my toe and the inside end of sandal toe. Wayyyy to much wiggle/slosh/swim room for comfort or safety. What happened to the sizing on this particular sandal/model, haven't a clue. Returned and replaced with a mere half size smaller. They fit like a charm.
My experiences (except for this odd size) with Keen sandals, have all been very good. They're durable like a work shoe, have fun colors, look good, and most of all, the support/fit is excellent. Really, I like my Keen!
