So I ordered the same size as my other Keens and it was too loose in the heel. A little play doesn't bother me, but my whole heel comes out. Something happened to the width or fit. I just left these new shoes lying around. I will either use them as slippers in the garage (very messy as they fit) or find some of the thickest socks imaginable and try to wear them in the winter. They should last forever though as I can't walk in them. Also, I should mention that I might want to buy direct from Keen as I also got Keen Anchorage boots which were a clean second (even without the box and all worn out). ) by Revain. So I may have defective shoes from a third party and will only buy from the Keen website from now on.
