Mike covered it.
It has that bulge shape in the spine to make it possible to get in because the carbon fiber is so rigid and you can’t open the throat enough. So the heel goes back instead of the instep pushing forward.

Perhaps this is why it looks like it pivots-

Don’t know why it’s like that. Perhaps because you could change the forward lean by changing that wedge piece. I don’t remember that part. We couldn’t take photos in the shop. They were very nice to show us around. It’s a
very small shop. Dave Dodge is also involved in binding safety.
That added sole piece goes over the two halves. The boot is assembled from 3 molded pieces plus the sole and spine, buckles, power strap.
That’s the big difference I didn’t realize till seeing it. They are not hand laying up carbon fiber cloth with resin. That would take an army.
They’re molding and punching for fit and assembling.
There’s some high tech stuff and basic boot shop tech. There’s a small robot involved, and the guy who did that setup/programming is in an old barn at the end of the road in the woods. He’s using high tech stuff to make things for the defense industry.
I remember seeing the cuff- it comes flat sheet, they cut the shape, then heat mold it. I believe the clog halves are a similar process, but my sieve memory forgets. Maybe
@TheArchitect remembers? We had a small group from the NEG that went there.
Part of the reason they stopped using dealers is the difficulty molding the carbon fiber construction. It has to be heated to a pretty controlled temp, so they have special equipment.

The shop near Burlington. That’s the other partner Bill Doble.
Speaking of Giradelli, they made a pair for him. In terms of wcup, the only one I know was Warren Nickerson, though I’m not sure he was actually on the US A Team when he was using them.
