Replying to Best boots for freestyle?

Hello,

I was wondering if anybody would be able to help me find the best park boots for me this season. I will be skiing the 2015 Icelantic Da'Nollies (170 cm) and I weigh 140 lbs. My shoe size is 11.5 and i believe my mondo is 29.5. My foot is a little wide, so if there is a 29.5 wide mondo that would be great! I would like to have a medium to stiff flex boot to be able to flex the ski easier to get more pop switch and for nollies (I have no idea if that makes sense). I have no budget, so any price is fine.

Thanks, and any help given will be very much appreciated!
