Nike Project (Red) Sneakers Classic Design (a project - discolored)

Size 7.5. I loved these, but they became discolored in storage. Perhaps someone knows how to restore? There’s also a small scuff on the toe of the left foot, and something on the satin strap on the right foot - might come off. Project (Red) was an initiative to fight AIDS, and they did collaborations with Nike, Gap, etc - these are from that. Smoke-free home, but I have a dog. No reasonable offer refused.
