My first thought was IMS as well - if you have big feet - they make a "low boy" peg - lower and back slightly from stock position to give you a little more room to the controls.
IMS makes a "pro series" and a "super stock" - I would recommend the pro series - they provide much better grip.
If you want to buy some bling - you can pick up some titanium YZ pegs on e-bay for not too much $$. It saves weight - but it is down low where you won't feel it - not a big bang for the buck.
