The Undefeated x Air Max 90 Pacific Blue released as part of a three-shoe collaboration. Inspired by technical outdoor apparel, the shoes upper is built with mesh and nubuck, but it forgoes the usual mudguard. A heel pull-loop provides easy on and off, while the tongue lacing system draws from the Nike Vomero 5. Underfoot, the speckled midsole houses visible Max Air in the heel for cushioning.
