A friend of mine sold me his old burton board and bindings. I've been riding and tinkering with the angles but realized yesterday that my boots aren't correctly centered. I get about a inch and a half of heel overhang but my toes are a good inch away from the sidecut.
Unscrew each binding and turn it the opposite direction. See if there's any difference based on which way they're facing. Might be enough to center it depending on how centered the base connectors are in comparison to the actual center of the boot. Might not be an inch of difference, but thought I'd throw the idea out there. Best of luck!
