Purchased a pair for a trip this past summer. looked masculine not to foo foo girly like alot of the shoes keen makes for men. Figured these would be a great travel shoe. Fit 11.5 was ok just tad small but ok. but, was still a roll of the dice when it comes to keen sizing they have a different sizing for every sole style they make very strange [ I have 6 different keen shoes/boots]. As far as comfort they are great. I can wear these all day long sitting, standing, walking, an excellent casual shoe for a man. Now here is the part I don't understand. The foot bed insert is beautiful. It is a medium soft,compliant foam with nice brown leather looking surface. after my first day of intense wear when I took my shoes off I noticed the bottom of my socks were solid brown. The dye from the insert is bleeding off into my socks and still are 6 months later, are you kidding me. does anybody at keen even test the products. other than that they are comfortable, look nice.
