What i'd really like to find is something you could mount to the end of the floorboard that would let you rest your heel in it while cruising down the road.
I have the Kuryakyn Cruise Arm Mark III. I am short (5'6") so I rest my heel on the floorboard and the toe on the Cruise Arm Peg. If you are taller the arch of your foot can rest on the Peg. I really like these for a nice clean look,
