If the guy would part with them for a grand, I'd still be looking at close to another $2000 by the time I molded and cast all the parts from them, but the parts would be 100% accurate. Unfortunately, they would all be what ever size those shoes are. Then there is the challenge of the uppers. Speaking of, I finally got all the materials including that special (#40 UV stable poly-spun, will NOT break with your hands) thread for my uppers project, so will be able to start on that again soon.
Really not sure as I have only seen the HCs but never test wore them. AFAIK, they use the same mid-sole/outer soles parts as the V2, just the heel cup is a new part due to it not having the branding.
What I am interested in knowing is about their XL and XS sizes as I really want a pair of US7s for true 1:1 display on my hover board. The US8s look good, but since working on mine, I want a smaller ankle buckle. So I have been looking at re-working my older vac-formed version as a base for a new rubber part over a reworking the CP 3D printed part. I am also reworking a pair of heel cups to have the 1" tall MAG letters and a more rounded shape. I am probably going to have to use sand on the part when I mold it to give it a texture close to the original parts.
