Nike ZOOMX VAPORFLY NEXT% 4 PROTO Nike ZoomX Vaporfly 4 Size: Men's 26.5cm. Comes with box and tags. Purchased in March 2025. Used in 10km and 5km races. Approximately 20km total running distance, including warm-up jogs. Weighing in at 163g, it's lightweight and easy to run in, allowing you to utilize your leg speed. You'll feel a significant evolution compared to the Vaporfly 3. I'm selling these as part of a decluttering effort, as I've purchased several racing shoes in the New Year's sale. This is a rare proto color that is not widely available and is no longer obtainable, so I'd like to pass it on to someone who will cherish them.
