I hadn't thought of that, my regular steel toes I ride with have enough vertical room for probably a good 1/2" of lift. My dad makes braces and artificial limbs and stuff. I'll have him whip up an insole!
On the lowering I would do seat before shocks. The Corbin single tour lowered me about an inch I think. One of the things I love about the rocket is how great it corners. That will change if you lower the shocks, maybe not for the worse who knows.
