99.99% of the time people are wrong about what size feet they have and consequently what size ski boot they should have. Definitely go to a boot-fitter (not a place that lets you pick the boot by yourself) and find out.
With that said, you are super limited with boots larger than size 32, Salomon X-Pro does go up to 34 in some models. You will be lucky to find a boot that properly fits you, so don't get picky or worry what the boot is "intended" for.
