From adidas's upper category brand "originals", here are the ZX500 OG. There is some overall signs of use. The outsole (black part = bottom) has hardened, and this is particularly noticeable on the left shoe. There is a single crack along the seam on the front, and it has been simply repaired. The heel entry area has been very simply repaired with tape. For this reason, these are being listed as junk for parts or for display purposes. ■ adidas originals ZX 500 OG ◎ Size: 23.0cm ◎ Signs of use: Yes ◎ Dirt: A little ◎ Deterioration: Outsole hardened/repaired ◎ Repairs: Simple tape repair on the inside of the heel entry area ◎ Odor: None ◎ Cleaned ◎ S79174 http://suniken.com/adidas/adidas-zx-500.html https://stockx.com/en-gb/adidas-zx-500-og-grey-red Other references (different models) https://sneakernews.com/2012/07/12/adidas-consortium-zx-500-og/ https://www.k-skit.com/item/adidas/running-series/zx500-og-m21873/ https://sneakerwars.jp/items/view/2699
