Product Details Grateful Dead Opti Yellow Dunk SB by Nike. I got this in the prerelease, thought they’d grow on my tastes, but never took a liking to the shoes so they’re for sale now. Like new. They’ve never been worn. The shoes are new, but the box is slightly damaged. More pictures coming. Store Policy Priority mail next business day Payment due within 25 hours. Refunds not accepted.
