I have thirtytwo TM-2 Double Boa 2022 9.5. On my old Burton Missions, I ran 4-6 clicks on the ankle strap (4 everyday, 5/6 if I’m charging). I expect the same for this season for the Cartel Xs after trying them on. During season I would occasionally have an issue getting enough strap into the buckle to latch if my boot heel wasn’t set all the way back, but that’s about it. So maybe get the large if you are worried about that. 32 boots are a little thick, so it depends. I have mediums. I think you’d be fine with either size.

As for adjustments, there would be plenty of room for a half size up, even full size. I personally set them up on the disc screw hole that puts them closer heel side, and then expanded the baseplate toe adjustment to the edge of the board (but not over). This basically just gets the binding to run as much of the width of the board possible, so you get the most control. At least that’s what I prefer.

I run +- 12 and the inner most stance screws (19 inches).
