I was messing around with a couple of different versions of Kastle's KTI (Marker) adjustable bindings the other day, and was comparing my wife's LX82's with mine side by side. The bindings are mounted the exact same (both K12's), but her toe mount is further to the rear of the ski because her foot and boot are smaller.
This equal adjustment of both toe and heel bindings to the center keeps any boot centered within the mount, but I read post after post here about mounting fixed bindings on a flat ski at a certain point, and from there the heel binding is mounted to accommodate for boot size. Which got me thinking that this is very much not happening with an adjustable binding since it is moving both heel and toe.
So my question is whether this adjustment can create a non-optimal boot position, or does the adjustable binding create a 'properly centered' mount no matter the boot size?
I understand that the experts aren't typically skiing this type of binding, and that you might say it doesn't matter for a non-expert. However, I noticed my wife's bindings had been improperly set by REI by 10mm (285 vs. her 295 boot size) and I fixed this. She noticed a huge change immediately in carving performance. Now that is fixing an error, but it has me thinking that if a smaller foot always sits farther back on the ski that there could be real effects, and an adjustable binding could be left at a set point for the toe only moving the heel for boot length.
A shop would never do this, but a user could. Thoughts?
