This is my son's fourth or fifth pair of Crocs and we've never had a quality issue before.  However, he left this pair on the beach in the sun for a few hours and the plastic melted/bent such that they are no longer at all comfortable.  If you do order these make sure to keep them dry and in the shade at all times.  It's worth noting that I'm ordering him another pair of Crocs in the classic style in the hope that those will be up to the quality we're used to.
