The Vomero 18 is Nike's soft, tall daily trainer. ZoomX foam sits on top of ReactX, the heel stack is 46 mm, and the 10 mm drop keeps the transition familiar. It is the shoe for easy miles when your legs are tired, and for long runs where protection matters more than speed.
You pay for that in weight. At roughly 325 g it is one of the heavier trainers you can buy, and it feels like it the moment you ask it to go fast.
It is not a tempo shoe and it is not a racer. Buy it as the cushioned half of a two-shoe rotation and keep something lighter for the quick days.
