ive ridden older flows. and all the cinches. i like that cinches open. It seems more logical that the binding will close down securely on the boot.
where flows only drop the highback... which means that, there has to be some wiggle room within the strap to get your foot in and out. may not be noticable but its there... and after a couple seasons. your boots will have a wear from it.
thats a total bummer. none the less i guess it makes sense to have a strap in to secure high/low points of the foot. but the flow concept seems really good. guess experince pays off
