A max-cushion cruiser built to help you defy gravity-literally. Your updated Men's Mizuno Wave Sky 9 running shoe upgrades to nitrogen-infused MIZUNO ENERZY NXT foam for even softer landings and springier takeoffs, while the FOAM WAVE geometry smooths out every transition. A stretchy woven upper locks you in without feeling stiff, and the ultra-durable X10 outsole keeps you going strong long after other shoes tap out. Compared to others in the lineup, the Wave Sky 9 is Mizuno's plushest, most luxurious daily trainer-perfect for when you want your miles to feel like clouds.
