A Pointe Shoe Assembled

I stumbled across this video in youtube some time ago. The makings on a pointe shoe.

Fascinating to see how those are made. Inside out first, then rolled so that the inside is where it should be, inside the shoe. And after that the glue is cured an the box hardens. Anyone else finding this fascinating?

I also found this pic, which made me wonder what kind of insole there is in my pointes. Especially if there is the cut area under the demi pointe spot. Sure feel like there ain't one. Rolling en pointe through demi is hard enough.

I guess I have to wait for my shoes to die on me to know. Waiting for the dissection a bit too much! *Drool*
