Nike Vomero Plus vs Mizuno Wave Sky 9:
Which to Choose

On paper these two look like twins — both score maximum cushioning (6/6), both are neutral with a moderate stability rating (4/6), both run plateless, and both sit in the same relaxed pace band (3/6). The differences are in the details and they matter. The Vomero Plus rides on a full-length slab of ZoomX at a 42 mm heel / 33 mm forefoot stack with a 9 mm drop, and weighs 285 g (men's US 9). The Wave Sky 9 is taller and heavier — a 44 mm heel / 38 mm forefoot stack at 295 g — and sits lower at a 6 mm drop. That combination tells the story: the Nike is the more responsive of the pair (5/6 versus 3/6), with a springy, gently bouncy ZoomX rebound that stays lively if you nudge the pace, while the Mizuno leans on nitrogen-infused Enerzy NXT over a firmer Enerzy carrier to deliver deep, forgiving impact absorption that returns only moderate energy — more cloud than trampoline. The steeper 9 mm drop on the Vomero rolls the heel through a touch more eagerly; the Wave Sky's 6 mm drop and thicker forefoot feel flatter and more planted. Use cases diverge too: the Vomero Plus is happiest at 10K to half-marathon distances and its softer, springier foam rewards easy-to-steady cruising, whereas the taller, plusher Wave Sky 9 is built to keep protecting your legs all the way through the marathon, trading a little liveliness for bottomless long-run comfort.
