There is a patent from 2000, now expired, for a laterally articulated ski boot. This describes a boot that is hinged in front and back of the ankle, allowing free movement side to side with the ankles, but rigid support with flexion and extension. Does anyone know if such a boot has every been prototyped and tested? The patent expired and is public domain. The inventor is John Best from the Tahoe area. The patent asserts that allowing skiers to freely invert and evert ankles to put skis on edge would make racers faster and make learning to ski easier. Of course every one "knows" that boots should be very rigid from side to side tohelp with edging. Or should they?
Laterally articulated ski boot? Has anyone made one?
The majority of boots these days come with some kind of off-the-shelf fixed position lateral cuff adjustment mechanism. With the manufacturer supplied tool, or an ordinary screwdriver, you can get a few degrees in or out alignment.
That was something - if memory serves me correctly - that was just beginning to trickle down to "main line" boots around 2000.
As far as a dynamic lateral cuff that flexes actively in ski, other than a leather boot, I've never heard of such an animal. I would think ankle injury would be a major issue, even if the articulation were limited to a degree or two, because of the impact involved when the ski edge engages.
Now, a system that allowed the boot to articulate forward, out of the Saggital plane by a degree or 5 might have some real benefit. There are some boots that have conceptual mechanisms for shifting the pressure points from directly in the saggital plane (12 o' clock) to, say 1 o' clock for rt boot and 11 o' clock for left boot. I don't really remember who, for some reason I'm thinking Atomic? But if I understand it, they are all completely static shifts, nothing dynamic.
Hopefully someone from the instructor ranks will come along and check this, but what your describing might occur as your COM comes over your outside ski and you start to fall over the the skis to initiate the next turn. Uphill ski will edge and come around and now is outside ski... and your pressure should still forward on the tongue, but slightly off to the side, at about 10 to 11 o' clock for right, and 1 to 2 o' clock for left.
As your starting point, read up on the topic of radial canting.
Did you pull the patent. Was there a drawing? I'm really curious about this simple because it seems to fly in the face of accepted notion of ski boots, but it is consistent with something I just learned about ice skates, that the upper laces are better left loose but the lower part is where you need to be locked down. If you ever see hockey players skating around with the top of their skates open, and you are thinking like a skier, you'd think they will break their ankles, but actually they are using that flexibility to control their edges in ways that you don't when skiing - you never cross one ski over the other to skate sideways or backwards - but the biomechanisc are similar...

That Seems Curious.
Sorry I can't contribute anything to the actual question. I'm just perplexed about the caps.
ummm not exactly, what I am suggesting is that as your turn right both boot cuffs would actual move left...... the exact opposite of you less support idea which has no merit in modern skiing.
No, I was replying to gdangel. I actually am not clear on what you were describing. I finished building a prototype tonight and I will ski it tomorrow! On dry land it is easier, and definitely more comfortable to incline the modified boot onto an edge. Ankle eversion/inversion movements are sufficient to modify the edge angle.
So yes, I can actually move the cuffs to the outside of the turn as increase edge inclination into the turn, or I can do the opposite. My ankles have more control over the fine tuning of the edge angle, but the boot is NOT floppy or lacking in all lateral support. The big question is whether I get more or less control with the forces generated by actually skiing. For safety and for a good comparator, I left one boot unmodified. So either I'll discover a breakthrough in ski technology, or I'll just discover how to break a leg and become better acquainted with the friendly local ski patrollers. All in the name of science. Place your bets, gentlemen....
