I can flip mine out with the toe of my boot. The bolt that the peg swivels on is a locker (?) type nut and the tension can be adjusted for your personal preference, by tightening or loosening the nut.
My Aero pegs are mounted all the way to the rear and I would speculate that there are about 3 more inches more adjustment to the front for those with longer legs (my inseam is 30"). Cool Hand Luke's are mounted more to the front so he would be better to explain about the comfort for those with longer legs.
