Sorry for the slow reply. The results were a little mixed, but mainly due to a couple of errors that after reading this you should be able to avoid.
The best shoe was the one I had left under the chair drying for a week. Unfortunately I managed to pinch the tong inside the shoe that made it very painful to climb in. I've since taken the rubber off and the pain has gone. Will put the rubber back on when I get chance. With putting it under a chair the rubber was level with the Dragon rubber and I didn't need to dremel at an angle (as much), but this runs the risk of a wayward tong.
The other shoe looked like this
Looks shit, but works really well. I've dremeled the rubber at an angle so that it won't peel off (after this shot). BTW It was very hard to de-laminate the other shoe, so the glue works really well
In future I would make sure to check the tong before weighting them down. This glue seems strong but isn't quick setting so you need to pack it or weight it. The rubber is great for toe hooking and IMHO better than paint on the dragon as it protects your bent toes. Stealth paint would be better on flatter shoes like the Velcro etc. Last but not least I wouldn't use gaffa tape to hold them down before weighting as this happens
Apologies for not getting photos of the decent shoe or for the shoe after it's been dremeled
