So it shouldn?t matter how they are worn. Decent quality. Not having any filler or cushion on the top, makes them ideal for riding. You can wear this in or out doors because the bottom of the shoe is rubber. It?s super loud. I would recommend Double AA barriers if your putting heavy things on the rack, for me a motorcycle jacket, so you can shut the door completely and it won?t risk it falling off the door. After installation I assume? Cant tell! I tried and searched online guide for factory reset and pairing. The sole was definitely durable and appeared like it would hold up well in and outside. I was very disappointed in these rugs.
