Okay here is me with the boots on. All strapped in how I would wear them if riding. The teeth get to about 7 left. And the straps line up in the middle. But still outlying worry is overhang of toe could be too much.
Hmm... the strap lengths look ok in that size, but the length of the baseplate still looks too short. Strange.
I'd still go with the large. That way you still get the same length options for the straps but you get a longer baseplate.
