I have no idea why people are saying that this shoe is running too small, THEY ARE TOO BIG! My last three pair of Keen shoes were size 8. These were too big, so I exchanged to a 7.5. Wait...then a 7. The heel is still too wide in the 7 which makes my heel slip out when I walk. The shoe itself is so stiff I'm not sure how I'll walk in  these. I'm not sure if I should risk breaking them in or should just return them, they are not cheap!
