Freshen up and toughen up your sneaker rotation for the fall, winter and spring seasons with the Nike Men's Air Max 90 Prm Casual Sneakers. Soft nubuck leather replaces the standard leather upper for a smooth touch that stands up to cold and wet conditions, and a versatile flax colorway that borrows a look from boots typically worn during these seasons so you can always match the vibe. And of course, a visible Max Air unit cushions each step for that often imitated but never duplicated walking-on-air feeling.
