Mine go bye bye when I put on high tops. In fact, shoes make the most noticeable difference for me (narrow toes feel way better, rubber toebcaps mess with flick, etc.)
Sizing down also messes me up until I adjust my flick, I usually flick way too hard at first and ease up until it feels right. Wheelbase really makes a difference too, I feel it's way easier to mob or catch too much friction trying to kf a longer board.
