I was expecting a great product considering we have bought our kids different Teva products before.  And I have to admit the shoes themselves are not bad.  But here are my issues:

First, the velcro strap on top rubbed my son's foot raw.  There was not enough adjustments and they just did not fit right. In order to remedy this we sewed felt on the back side of the strap.  This helped.
Second, the heel enclosure is made from the same durable material as the rest of the shoe and after one day at the beach his heals were bleeding from all the rubbing.

I would have thought with the velcro strap and the elastic laces that we would have been able to adjust them to fit better, but we finally gave up.  Sorry Teva, its back to the Keen's for us.
