sorry, i didn't catch that gas pedal was already adjusted
the fit is fine and will work with no issue.
now, if your feet are still growing, i'd return them for a size large in the expectation that you'd need a bigger binding.
If you got, Burton boots, you're in a size medium until you hit a size 11.
this is why we really believe in getting gear from a local shop if you can, as you can physically check the fit of anything and weigh all options.
