Only used twice on my 2006 FLX (bought a new board). Huge improvement over the older Underground footstraps and pads. Totally integrated footpad with dual strap for lots of foot-cinching power.
The real beauty of the integrated system is in the retainers which fasten the strap's stainless steel D rings through the pad at 90 degrees to the board.
Retail $140 USD. Asking $75. Send me a PM.
