Howdy,
My wife would raise a the same complaint after a couple of hours. I got a new set of passenger pegs from Twisted Throttle. They helped a lot, but I was worried that I would drag her toe before my peg feeler, when the were set at the lowest position. I have the pegs set farther forward and not as low now. There is a lot of adjustment in the system. Hope this helps.
