And it is the same weakness on all of the Keen shoes/boots I own.  That weakness is the lacing system.  It is archaic, and it is not at all easy to achieve uniform snugness.  I own 6 or 7 pairs of Keens, and I have the same complaint about all of them.  That said I like the fit and cushioning.  The big boxy toes work just fine for me.  I bought them for hunting boots not hiking boots and they have been supurb once I finally get them laced.  I guess I get past the laces, as I do keep buying Keens.
