i just post a review with mine on the BINDING REVIEW section and the shoe horning is a bit of an issue for me but,as i said i had the same issue with my flow 5 too when i had it new. It was my first day with my NX2 so my boot heel
will break in the more i ride it. my highback stayed down with no issue too. boot size is 10 and i got the large size binding,no pinching issue with mine either. As Oldman said, it is comfortable once your locked in.
