An independent study published in 2022 by Joubert compared different brands of super shoes and found that the Nike Vaporfly improved running economy by about 2.7 percent at speeds of 16 kilometers an hour (or 6:02 mile pace) compared to a control shoe.

Running in a high-efficiency shoe like the Vaporfly means less wear and tear on the body, helping you perform your best during key workouts. You'll still need an adequate recovery shoe in your rotation, but we strongly recommend lacing up your Vaporflys for speed workouts and tempo runs to reap major training benefits.
