NOTE the pix above does not show that the big toe oversized support as is normal in Keen's has a lip which extends down to the 2nd toe.  If your toe is long enough is reaches under the covered area.  If too small you are ok.  If you toe just reaches the lip cover it causes the toe to continously run against the overhang.  OOOW.  Also I tried the locker return to a suggested Amazon drop off in a 711 in Costa Mesa, CA.  The store no longer exists adding more problems to the purchase.
