These hiking boots are not for my feet.  I like keen casual shoes because of the comfort of the wide toe box so I decided to get keen hiking boots.  The boots are the proper length at a size 13 but the volume over the instep and heal is too large.  At least that is how I have diagnosed the problem.  I cannot lace the boots such that my toes do not come in contact with the front of the boot going down hill after wearing them 10 minutes or so. I spent 3 weeks in them in Tibet and 3 weeks in them in Equador.  All were day hikes but I had the same result in those mountainous environments. I see no structural problems.  They are just uncomfortable.  I am trying some other inserts to see if I can fill the shoe a bit more but I am also looking for a new boot.  I bought the Targhee II hiking shoe at the same time for the same reason.  The comments apply to them too.
