I have multiple pairs of the Keen ultra in womens size 10.5, but when i saw this colorway in mens, i needed to try it. I ordered an 8.5, 9 and 9.5 as ive found that Keens vary in size in different colors. 9.5 was obviously too big, and neither the 8.5 nor 9 really fits the same way as my 10.5 womens, they seem narrower. On top of that, you cant tell from the online photos, but the main shoe stitching color is different on the left and right shoes, they swapped the colors. At first i thought they made a mistake but when all three pairs had it i knew it was intentional. I don't like it. Other than that, the shoes would be comfy.
