I returned my first pair of these, had ordered size 9.5 and they were way too big. I got a 9 this time and they're still roomy.  I probably could have gotten by with an 8.5 in this shoe.  My heel slips, but it's not something that would deter me from wearing them.  I needed thicker socks, but that's just a personal preference.  This is my first pair of non-sandal Keens and they have the characteristic toe cap and good arch support.  I never feel unsteady or wobbly.  The photo does not agree with the contents of the box, Slate Black is a medium brown color, not the rich chestnut depicted, which I was hoping for.  No matter, I wear them with jeans and khakis, probably will with my shorts later in the year.  I would buy them again in any color and expect the quality I always get with Keen.
