Just measured the overhang with boots on my cousins board that I've been riding thus far and his is 0.5 toe 1.5-2 heel. So I'm gonna leave it as is.
Only difference between our setups is his bindings end at the boards edge, and his boots have an upward curve on both ends.
However my bindings have a strange shape and when angled, they have base plate overhang too. My rear binding is +6 and has no overhang, while forward binding is +15 and has 0.25in base plate overhang. Also my boots don't really have an upward curve.
So on the carpet test I can get up to about a 35 degree angle either side. Anything above is a no go.
Dunno if this will be an issue, and if it is, if it could be remedied by trading the L/XL binding for a M/L. Just don't know if it would fit, as the M/L is rated for 10 boot max.
