I have the Keen Briggs II in a size 12, so after reading reviews I ordered these in a size 12.  Good looking shoe and well made, but much narrower than the Briggs.  The tongue is sewed tight to the shoe by the lace loops, so it's not like you can loosen the strings and widen it out a little bit to get some extra room.  Hate to do it, but have to return them.
