Our Verdict
Nike Vomero 18
Brooks Glycerin 23
The Nike Vomero 18 is a better shoe than the Brooks Glycerin 23. The Nike shoe's rockered heel smooths out each landing, and its cushioning holds up better over long distances, so it stays more comfortable deep into long runs. Both shoes feel similarly stable and weigh about the same, but the Brooks has a much roomier toe box, which makes it a worthwhile option for runners who like extra space up front.
