^^ That's exactly what they are - there's a photo in 'Upcoming/Recent Shoe Releases.' It's an all black Pro Model (the high top shelltoe that has been called that since the 70's or whatever, not a 'pro model' like Nora and Tyshawn have), where the black appears to wear away to purple.
They did a couple colourways of the Pro Model ADV as part of the skate line when they did the Superstar ADV a few years back. They haven't been making them for the skate line much, but Kader has skated the non-skate version of it a fair bit. The shoe isn't for me, but I hope they sell a million of them just because I know how much many of my least favourite people in skating don't seem to like Kader for whatever reason (I know exactly what the reason is).
