Have been wearing Keens for years.  I found the toe box on these to be smaller (not as wide) than my other Keens and they are less comfortable, too, I can only manage a half day in them before I need to switch to another pair (I'm on my feet a lot).  Would return them if I could for a more comfortable style and a better fit.  I'd rate them between a 2 and a 3 for me.
