Even on the extended 5,000 mile trip the kayak never moved and was never marred by these racks. These sandals are pretty extreme on the arch support. If it changes Ill update my review, but for now? These things are on par with mid-range gaming headphones, if not significantly better by crosstalk and recording noise cancellation alone. Months later, I found a box of items waiting to be returned only to find out that it was too late. For some reason the label on the heal on the inside is a super scratchy metallic material. Excellent shoe for work ro wear with trousers. I love the extra elastic placed in the strap and a real buckle (instead of velcro-like fasteners). Thank you Dansko! I?m very happy with this. The problem is the mounting boards on the back of cabinet.
