And here are the two new parts after all the flashing has been removed. The part on the right is the master part and the other two are the clones.

I am glad I removed most of the flash whilst they were still soft. Now that they have set, they are pretty hard. As I said in my video, I don't think it is important for these to be soft. The strap and buckle are part of the support. The new heel cups will have to be soft to allow flex when you walk.
