Would you say a boot with a lower hinge point would be more appropriate for most people than the standard hinge point?
I'm thinking that if the standard hinge point is too high, the heel will have a tendency to lift. That would be very bad if heel pressure should be dominant.
OTOH, if the hinge point is too low, it would just make the boot easier to flex overall. (added leverage)
The hinge point and ankle joint in full alignment would seem the best arrangement, but failing that, too low a hinge point would be better than too high.
That would suggest another decision point in boot fitting, making the process even more difficult considering the narrow range of choices available at the shops.
From a personal perspective I think is one of the biggest issues for me in how a boot flex feels and how it integrates with my own movements. Fit and how the boot flexs with my geometry is what I go by first. Later, RicB.
