I've worn Nike on my feet, almost exclusively, for sport for 20+ years.  These have to be the most uncomfortable shoes they've ever produced.  I actually have to wonder if they are actually a Nike product, or a knockoff.  The shoes feel as if someone has worn them for 6 months and contoured the insoles to match their foot, as there are grooves in the heel and toe pad, just like my FS Lites contoured after 3-4 months.  I do have somewhat flat feet, and I have only worn them for a day so that may change.  Either way, I am hoping a decent pair of insoles will resolve this nearly $100 mistake, if not, maybe you'll have better luck (or the right foot shape).
