I have Rulers (size 10) and Targas (l/XL). there is much more play with the boot in the Targas side to side than there was on my old Burton Missions. The size 9 may work with the s/m size, but you'll probabbly be maxing out all the adjustments, and I don't know how well that will work. Also, the toe strap cap digs into the corner of my toe instead of wrapping around it. This might be solved with further adjustment, but maybe not. I'm still a little undecided on how I feel about the Targas. I feel like I had more response from my Missions, but I'm also riding a new board too, so between the new board and bindings there's a lot to get used to.
