Thanks for the link Mathman! It's amazing what sort of interesting information can get hidden in a 9 page long topic; I usually don't keep up past page 3. I never would have guessed that the topic "Article on Sasha Cohen" was where to look for info on the hinged boot.
I heard that Bill Fauver (Leann Miller's pair partner) who teaches in Nashville, was working on just such a boot. I heard this from a woman who works for US Figure Skating.
Nthuz,
If you find out anymore information on the figure skating hinged boot Bill Fauver is working on, would you please either post it or PM me? As Mathman will attest to, I have been going, well, ntuhz trying to find info on the FS hinged boot since I saw a report on it prior to the Olympics on NBC news. If you do a search on any large search engine, all you can find are links to info on the hinged speed skating boot, which is a completely different design from the hinged figure skating boot and works by having the back part of the boot hinged on so it makes a clapping sound and allows the speed skater to gain more speed. The FS hinged boot is hinged at the ankle to allow for greater ankle range of motion, which supposedly will allow the skater to use more of the ankle to get up in the air for jumps and also allow the landing forces to be more evenly spread out among the low back, hip, knee, and ankle rather than focusing so much force on the hip.
On the NBC news report they showed a sports medicine specialist and figure skater (woman in her 50s) skating on her own design of the hinged FS boot and discussing the results of biomechanical analyses they'd done with the boot, so I just assumed that soon enough I'd find something about it in the sports medicine literature or somewhere on the 'net. But nope. This really interests me, as you'll see if you go to Mathman's link to my posts, so any crumb of further info you hear, I'd appreciate your posting it or PMing me. Thanks!

It's not the same thing. The "clap boot" used in speed skating allows the heel of the boot lift off the blade, while the blade itself stays on the ice. This allows you to skate faster, as I understand it, because...
The reason that you can skate on ice at all is that the friction between the blade and the ice melts the ice a little bit, creating a thin film of water that you actually skate on. (Think of liquid water molecules as little ball-bearings.) Ever time you lift you skate from the ice and put it back down, you have to remelt the ice. With the hinged skating boot you get a longer continuous edge with each stroke before the blade actually leaves the ice, if at all.
It was first used in the 2002 Olympics, if you watched the time trials, every heat set a new world record as a succession of better and better skaters took the ice using the new equipment.
