I’d love to hear what other Salty Peeps think of the 4%s! Yes, I bought a pair. They are still in the box because I don’t want to “mess them up”. I am hoping this isn’t going to be like the “good china” that I never use?? I had planned to run my goal marathon in them but can’t bring myself to practice with them. Who else has VFs and how did you get the nerve up to take them out of their box?
Nike’s Vapor Fly 4%s are the new(esh) shoes that many elites are wearing. The Vapor Flys were created as part of the Breaking2 project. In 2018, over half of the podium finishers of the Marathon Majors were wearing Vapor Flys. The shoe has a special foam and also a carbon fiber plate that supposedly increases running economy by 4%. They cost $250 and they wear out after 100 miles. I bought them anyway and I do think they are pretty amazing.
