Nike Zoom Alphafly Next% vs Saucony Endorphin Pro

We are so excited for the official re-launch and re-stock of the new Saucony Endorphin Pro and the Nike Zoom Alphafly Next%.  Two high-performance running shoes made with our Pebax® technology!

We've all seen the Nike Vaporflys and Alphaflys on running podiums these past couple years, but Saucony has entered the game to challenge Nike's dominance.

If you are a runner, this comparison will help you select your next racing shoe! 

Alphafly vs Endorphin Pro : what's the same?

PEBAX® technology:
Both shoes have an excellent energy return due to their foams made of Pebax® polymer. Nike calls it ZOOMX, "The Magically Energetic Foam" that you can find in all their ZoomX shoe collection. Saucony calls their Pebax® polymer-based foam PWRRUN PB.  Their foam is directly injected in the midsole of the Endorphin Pro, making it the lightest midsole the brand has ever introduced in a running shoe. 

Carbon Fiber Plate:
This additional element helps create the energetic and springy magic for runners.  Both the Alphafly and Endorphin Pro have a single, full-length carbon-fiber plate inside the Pebax® polymer foam midsole.  This combination brings the diving board propulsion effect while maintaining a soft and cushioned impact for your comfort.

What's different?

Foam thickness:
Measuring 35mm in the forefoot and 39mm in the heel, the Alphafly Next% is one of the thickest shoe on the market, narrowly avoiding World Athletics ban on shoes competition. It will take you a few miles to get used to this chunky running shoe.

In comparison, the Endorphin Pro is quite a bit shorter at 25mm in the forefoot and 33mm in the heel (depending on sizes). Dimensionally, they are much more like traditional running shoes so they shouldn't take too long to get used to.

Doing some quick math from the number above, the Alphafly Next% has a 4mm drop, while the Endorphin Pro keeps a standard 8mm drop. We know this is a key factor for many runners when selecting a race shoe, so pay close attention to the specs to find what's right for you.

Thanks to the lighweight Pebax® elastomer foam, the Alphafy Next% only weighs 7.4 ounces, while the Endorphin Pro is 7.5 ounces (size 9)... but who could really tell the difference? 

If you are a competitive marathoner, you may be totally ready to spend $250 for the Zoom Alphafly Next%.  But if you want to save a few bucks, the Endorphin Pro is a bit cheaper at a price of $200.
