I purchase the QUOC Restrap Sandal in Black. Unfortunately, they were defective, and I had to return them. The main straps are held in place by a small strip of leather and rivets. When I received the sandals, I removed them from the box and tried them on. The rivets on the right sandal immediately when flying across the room. It seems Quality Control missed this defect. I'm actually glad they failed immediately as I don't think using rivets is a good design, it seems they would be prone to failing in the field. This cost me $20.00 in shipping essentially to try something on and return it.
