These are the worst shoes I have ever purchased.  The toe box is extremely narrow, the material doesn't give.  I can't even wear these for 10 minutes without them hurting my toes.  The whole shoe is really narrow.  I really wanted to like these shoes because the footbed is INCREDIBLE, and so comfortable.  But even with that redeeming quality, this is awful.  The mesh around the toes is really sharp, and doesn't expand over time at all whatsoever.  Truly disappointed with these shoes.
