Fit well ... The major "breaking in" will be the strap.  Too loose, it rubs a little bit, too tight, it rubs a lot.  Once the strap is broken in, the shoes will be fine.  I have several pairs of Tevas and they fit better than some ofthe others in its class.  For me, TEvas work better than Keens.  I find that Tevas fit my FOOT, and Keens, for example, my foot has to form to its last, if that makes sense.
