i just bought a set-up for my gf at my local shop. The guy mounted the bindings forward towards the toe side edge instead of the center. The boots have plenty of room to move back without going anywhere near overhanging. I've always assumed centering the bindings in the middle of the board was the only way to go. Does anyone else do this?
Try this trick and spin it, yeah
Your head will collapse
In my limited experience I try to centre my boots on the board. Which in my case because I have boots that are close to the maximum size the bindings can take, means I think I set my bindings closer to the heel edge.
You also said that the boots have plenty of room to move back without overhanging? Are you saying that there is no overhang at all as I would have thought that in that case the board is too wide?
Binding centering is not what is crucial. It is the boot centering. As someone above stated, sometimes the bindings need to be off-center in order for the boots to be centered when strapped in. So go at it.
