The shoes themselves were comfortable but the liner inside was only attached at the heel.  After walking just a short distance at a water park, the liner started creeping under the arch of the foot, which was very uncomfortable.  We're going to try gluing it down under the ball of the foot to see if that makes a difference.  I really liked the adjustable strap at the back and they were very easy to get on and off.  If only they'd fully secured the liner, I'd give them more stars!
