4 stars and not 5 only because they run a little snug.  I have several pair of boots and shoes by Ariat and this is the fist where that has happened.  Not uncomfortably snug but a little snug especially in the toes.  I am guessing it may because the waterproof lining takes up some space and doesnt allow the leather to stretch as much.  Consider a half a size up, but then it might slip.  Otherwise they are very comfortable, supportive, great cushiony but firm non slip sole.  All around perfect.... but run a little smaller than usual.
