This might be Nike's best Vomero yet, and arguably one of their best overall models in many, many years.  The biggest change is the addition of ZoomX foam in the midsole, which is stacked on top of responsive ReactX foam for a cushioned, yet very springy ride.  Overall, the shoe adds 6mm of cushioning to the stack height, so it's an immediately noticeable difference (as compared to version 17).
