New, Never Worn Nike Dueltone Racer Size 10

Nike DuelTone Racer Size 10. Never worn, no box. I like to think I’m a size 10 in Nike’s but I am not. Fails me every time. The pink on the back looks slightly dirty for some reason (see pic) and there seems to be a little noticeable shoe glue on the white rubber but they’ve only been sitting in my closet for too long hoping my feet would shrink. It’s not happening so it’s time for them to go.
