The car top bag came with clear instructions as to where to place it on top of the car and where to place the straps.

These cross bars are meant for this car, so I would think the manufacturer could have at least made them to a specification where they properly fit. The most comfortable shoe I have ever worn in my entire life (and I am 65)! These shoes feel great. 1, its definitely artificial sounding.
