In the elite world of carbon-plated super shoes, two names dominate the conversation: the Saucony Endorphin Pro 3 and the Nike ZoomX Vaporfly (Next% 2 / 3). These high-performance racing shoes are designed for one purpose—speed. Whether you’re running a 5K or a full marathon, choosing the right shoe could mean the difference between a personal best and falling short. But which of these top-tier racers truly reigns supreme?
This in-depth comparison breaks down the key differences and similarities between the Endorphin Pro 3 and the Vaporfly to help you decide which is best for your racing goals.
1. Design Philosophy: Power vs Efficiency
- Saucony Endorphin Pro 3: Engineered for aggressive propulsion with its SPEEDROLL geometry and carbon plate integration, the Pro 3 is built to deliver an energetic, rolling stride.
- Nike Vaporfly: Known for its weightless feel and energy return, the Vaporfly emphasizes pure efficiency. It’s designed to conserve energy over long distances through ZoomX foam and a curved carbon plate.
Verdict: Pro 3 gives a more “push-you-forward” ride, while Vaporfly gives you a lighter, bounce-based rhythm.
2. Midsole & Cushioning: PWRRUNPB vs ZoomX
- Saucony: Uses PWRRUNPB foam, a super-light, high-rebound PEBA-based material. It provides a soft yet controlled ride with excellent energy return.
- Nike: Features ZoomX, a proprietary PEBA foam known for its extreme softness, bounce, and ultra-lightweight feel.
Verdict: ZoomX is softer and springier, while PWRRUNPB feels more stable and slightly firmer. Preference depends on whether you want cloud-like softness or a grounded pop.
3. Weight: Who’s Lighter?
- Endorphin Pro 3: ~7.2 oz (204 g for men)
- Vaporfly Next% 3: ~6.5 oz (184 g for men)
Verdict: Vaporfly wins on weight—especially important over longer distances when ounces can add up.
4. Carbon Plate Performance
- Both shoes use full-length carbon fiber plates for propulsion and structure.
- The Vaporfly’s plate is more curved, enhancing the rocker effect.
- The Pro 3’s plate works in tandem with the SPEEDROLL tech for a forward-driving feel.
Verdict: Both offer elite-level propulsion, but the Vaporfly feels more “fluid,” while the Pro 3 feels more “explosive.”
5. Outsole Traction and Durability
- Saucony: Improved rubber placement gives solid grip and durability for a race shoe.
- Nike: Minimal rubber coverage to save weight, but it can wear faster and provide less traction in wet conditions.
Verdict: Pro 3 takes the edge for better outsole durability and wet-surface confidence.
6. Upper and Fit
- Pro 3: Lightweight mono-mesh upper, breathable and supportive with a performance fit.
- Vaporfly: Flyknit or Vaporweave (depending on version), ultra-light and breathable, but can feel looser for narrow-footed runners.
Verdict: The Pro 3 offers a more secure lockdown, while the Vaporfly prioritizes airiness and flexibility.
7. Stability and Ride Feel
- Saucony: More stable, thanks to a slightly wider base and firmer feel.
- Nike: Cushier ride with less inherent stability—can feel wobbly for some runners on turns or uneven surfaces.
Verdict: If you need a stable platform for mid/long distances, the Endorphin Pro 3 is the safer bet.
8. Price Comparison
- Saucony Endorphin Pro 3: ~$225 USD
- Nike Vaporfly Next% 3: ~$250 USD
Verdict: Slightly more affordable, the Pro 3 offers tremendous value for performance.
9. Best Use Cases
- Endorphin Pro 3: Best for runners who want a stable, aggressive ride—great for marathons and fast tempo runs.
- Vaporfly: Best for runners chasing maximum energy return and minimal weight—ideal for PR attempts and elites.
10. Which Racer Should You Choose?
Choose the Saucony Endorphin Pro 3 if you want:
- A more stable ride
- Slightly firmer cushioning with plenty of rebound
- A secure, locked-in fit
- Better traction and outsole durability
- A more affordable super shoe
Choose the Nike Vaporfly if you want:
- The lightest, most responsive racing shoe
- Ultra-soft ZoomX cushioning
- Maximum energy conservation
- Proven elite race-day pedigree
- That “floating on air” feel
Final Verdict: It Depends on Your Running Style
Both the Saucony Endorphin Pro 3 and Nike ZoomX Vaporfly are outstanding marathon-ready racers. The Vaporfly reigns as the gold standard for lightweight, bouncy propulsion—but the Endorphin Pro 3 offers better stability, traction, and value. Your decision should come down to your foot shape, racing goals, and ride preference.
Either way, you’re lacing up a podium-worthy shoe.
