I ordered a half size up based on other reviews I read and hoped for the best.  A little tight at first try, but I figured they would break in well.  After wearing for about 15 minutes, I had to give up.  My feet were losing circulation and starting to feel numb, and the pressure was mainly from the top of the shoe.  Foot bed not as roomy as I am used to with Keens either, and that's one thing I count on!  So, if you have more narrow feet, these might be perfect for you, but if you have wider feet, keep looking.  I was disappointed to have to return these, since they seemed so cozy.
