I normally wear a 9.5 in Keen shoes. I have about 10 pairs. Boots, mary janes, hiking shoes...
I couldn't even get my foot in these and get the ankle strap on my heal. They are made super small. Keen shoes have been inconistent in sizing lately. I purchased a pair of H2 Newport in a size 7 for my son and got my foot in there no problem.  I wear a womens 9.5 for reference.
