I had to go to Dick's Sporting Goods to try on 3 different pairs to determine which fit was right for me.  1.  Whispers -- my small pinkie toes were sticking out of sides, my heels kept falling out back and they had no/little arch support.  2.  Newport H2 -- very heavy, okay arch support, heels had minimal support -- I understand why people have said the heels wear quickly.  3.  Venice -- these were a great fit for my narrow feet and high arches.  These are lighter Keens with good heel support.  There is more rubber at the front of the toe -- but not anymore than the Newport.  I wear an in running shoes, but bought a 7.5 Keen that fit perfectly.
