As far as hardboot carving angles go,I always followed the “put your toe and heel as close to the edges as possible. This makes sense from a leverage point, but I’ve recently in creased my angles to 65-68 front and 60ish rear ( used to be 60/54 )with some underhang on the front heelside to eliminate bootout (20 cm board).These angles have freed up my ability to angulate and eliminated front leg knee pain. Just saying sometimes a little experimentation can really make things work. My heelside was always very strong, but toeside not so much. Especially transition from heel to toe. Now with new angles , transition has become more seamless. Angulation is much better on toeside- more powerful toe turns. Could always dump speed on heelside but not on toe. To be able to dump some speed on toeside is great now able to keep a more steady speed Not pimping any specific angles, but just saying if things aren’t working great, might pay to change things up a bit. It’s only taken me 13 years to figure this out:).
