I have big feet and with boots on the stock shifter is too close and too far out for me to operate it comfortably. I run a steel IMS shifter for an XR400, and what I love about it is that it moves the shifter peg position inboard quite a bit. This buys me lots of room for my foot, and when I want to shift I just need to point my toes up or down and I can shift with the inside of my foot/big toe. The only change I made to it for fitment reasons was replacing the hex head pinch bolt with a button head allen bolt.
A couple of pics here that show it.
