When I first put these on, they felt so good.  I walked around the house awhile and they felt great!  I decided they were keepers and headed for the truck.  When I pushed the clutch pedal, "Ouch"!  The string eyelet rivets are exposed inside the shoe.  When you flex your foot, the metal rivet bites into your foot.  Or it did me.  Maybe it's just the way my foot fits the shoe.  However, in other shoes I have that are similar, the rivets are inside the shoe lining or the tongue gusset is between the rivets and your foot.  I had to send them back.  They were really comfortable.  Bummer.
