Both shoes are now off the soles. Both toe boxes have been removed and I did this with no tearing of the fabric

All traces of the original electrics have been removed. Did you guys know there is a 2nd rectangle hole hidden behind the heel cup directly below the charge port hole? This how the wires go into the sole.
Both heel cups have been removed and are ready for modding, again no tears. Sometime in the next week, I will pay a visit to a friend with a milling machine and get him to cut the letters M A G into a piece of perspex based on the graphic I used for hand cut letters. From there, I will be able to flood the cutout with elastomer to make a new master part. I can then mold and cast that. I am also going to thicken up the inside centre of the heel cup a bit and add a small lip to allow it to be attached to the outside of the mid-sole to give that "fat ass" look. This might take a few goes to get right. So the final result will be a modded heel cup with 25mm (1") tall MAG. I am keeping the original NIKE as I quite like those letters. I had to replace mine on my wear pair because in the build up process, I had to cover them in rubber. The goal is to keep the round shape, but make it stick out more and keep the texture of the part. I want to cast these in a light grey that is the same colour as my mid-soles are now. All that is needed is to apply splat and paint the letters. I may even be able to mix the colour needed first, cast the letters, let them cure before pouring the grey. This is how CP did his.
Both ankle bubbles have been removed from the heel cups for modding. Although I did attempt this a while ago, I was not happy with the results, so will be re-doing the master part and molds. Basically I want to keep the rim that prevents this part from poppoing out, but I want the depth to be the same as the part when it has been trimming and pushed through. I also want to make the profile a bit rounder front to back. Because there is both a left and right, I will need to be careful to keep the balance.
I'll post pics as soon as they are uploaded.
