This is a very impressive shoe. I’m a long-time Vomero user and picked up the Zoom Fly specifically for tempo days and long runs, keeping the Vomeros for easy recovery. While it lacks the plush cushioning of the Vomero, it’s much more stable and really encourages a faster turnover. It requires a bit more of a break-in period compared to the instant comfort of the Vomero, but it definitely feels like an upgrade for my performance. Plus, they look fantastic in person—much better than the photos!
