These shoes are just fantastic.  I wore them to teach an all-day training session and my feet felt fine at the end.  They have a lot of padding in the ball of the foot and tons of room in the toe box.  The extra strap helps keep them from sliding off my heel, like many slingbacks will do.  I love these shoes!

Only comment is that they scuff easily.  You can rub them out with your finger (at least in the brown color).
