Saucony Endorphin Pro vs Nike Vaporfly: race shoe compared
The short answer: Both are carbon-plate racing shoes competing at the top of the distance running market. The Vaporfly is more widely used at elite level. The Endorphin Pro is a credible alternative that often costs less and suits runners who find the Vaporfly's geometry does not match their stride.
The foam difference
Nike Vaporfly uses ZoomX foam — polyurethane-based, extremely lightweight, highly energetic. Saucony Endorphin Pro uses PWRRUN PB — EVA-based, also highly responsive but with a different character. ZoomX is generally described as bouncier. PWRRUN PB is described as more cushioned at the same responsiveness level.
Which is faster?
Studies have shown the Vaporfly to be among the most efficient shoes for elite runners. At recreational pace, the difference between the two is likely smaller than running form, training, and race-day conditions. Some runners respond better to one or the other based on their stride.
Verdict
If you have tried both and respond better to one — buy that one. If choosing without trying both: both are legitimate carbon race shoes. The Endorphin Pro often comes at a better price point and is the right choice for runners who find the Vaporfly's geometry does not suit their stride.
