My daughter loves these shoes and they seem like they would be very comfortable. She wears orthodic inserts, and these have removable inserts so that I can easily remove the factory ones and replace with hers.  One thing I want to point out is that these are very breathable-- the mesh sides are great for the summer, but will not be very warm in the winter.  My only complaint about these shoes is that the velcro strap is too long.  It is very stretchy and when I pull it tight as far as I would ideally like (to tighten the shoes), it goes almost past the velcro pad, leaving hardly any room for the 2 sides of velcro to lock onto one another.  My daughter has average width feet, so this would definitely be a problem for anyone with more narrow feet.  Also, I'm concerned that over time the strap will get stretched out so much that it will no longer stick.
