I LOVE these shoes, but alas, due to my bunions, i've learned it's best for me to have a 12mm heel to toe offset.  these are 4mm.  and adding an insert just made my heel slip out of the shoe, but i LOVE the vibram soles.  great quality.  oh, i have very high arches, i would have had to add arch support inserts to these shoes.  still looking for my shoe destiny.  :-/  if anyone knows of 12mm heel to toe offset vibram sole trail running shoes that are wide in the toebox...let me know!  :-D
