Yes strap is at the slot furthest from the toe and is set up so that the cap is at angle over the boot. Won't stay put.
Not gonna spend another $40 to fix something that should work out of the box. Time to go a different direction.
So spending $260 on a new set is better than a $40 fix?
Second choices would be Ride Capo, Rodeo, or the Raiden Phantom.
