My first fur Crocs I had brought in the Metro. After these had life behind I ordered up new ones. Surprise! This series just makes noise. An audible groan noise not at every step. When I go to bed later than my wife, I pull these things off the master bedroom, because you're a light sleeper and even the one time or another has become awake. Property then times Croc.eu written and described my concerns. After a short comunication via email I got 3 photos sent from the still existing models and colors from which I could choose my the corresponding pair. A week later, the free replacement. Thanks again to at Amazon for their support and especially to Croc Europe for goodwill. Now all is well. She sleeps through!
