The straps are adjustable so I can tighten or loosen them if needed. They slip on easily and dont slide off. I used the hitch to attach a carrying grate for camping and the tailpipe melted the tarp on the grate. The comfort is great and I think the AirWings do an excellent job of keeping the headphones in place when working out. We received them as I ordered them for my daughter because she can only wear sandals with back straps to school. Going to screw it back in, the screw had lost most of its threading, so didnt end up secure - wobbled. Perfect fit and extremely comfortable and supportive! They?re very comfortable on my feet and they look nice as well. It?s hard and secure and everything fits in it nice a snug. If this had happened to me while riding outdoors, the results could have been serious.
