Now that I think of it, For the Metallic 5 Sample, I believe the more defined heel bumps is why anodized look didn’t make it to final production. The OG 5s ankle bumps were flatter and weren’t as defined, so the entire piece was anodized. With the retro sample, the anodized every part of the piece but the bumps. It doesn’t look as clean as the 1990. Maybe that’s why they didn’t do it. For the 6, that wouldn’t be as much a problem aesthetically
1990
2016
If the bumps were anodized completely, it’d look like this.
The actual release pair didn’t sell out quick anyway, so maybe they should’ve just added it.
