Introduction
The Nike Air Zoom Alphafly NEXT% is not just a running shoe—it’s the pinnacle of Nike’s innovation in marathon performance. Worn by Eliud Kipchoge during his sub-2-hour marathon feat, it’s engineered to break barriers. But with colorways like the vibrant ‘Watermelon’, it’s also turning heads far beyond the finish line.
Featuring bold accents, cutting-edge technology, and a fashion-forward silhouette, the Alphafly NEXT% ‘Watermelon’ is both an elite racing tool and a statement-making fashionable sneaker for serious athletes and sneaker lovers alike.

Design: Aesthetic That Pops
The ‘Watermelon’ colorway blends function and flair with a fresh, energetic palette that lives up to its name.
Visual Highlights:
- Light white/green Atomknit upper that looks breathable and fast
- Vivid red-pink Zoom Air pods at the forefoot mimic watermelon flesh
- Mint green midsole foam offers balance and color contrast
- Black carbon-fiber plate peeks through translucent sole layers
- Sleek, aerodynamic lines built for speed and beauty
Despite being a serious performance shoe, the aesthetic makes it feel like a pair of stylish sneakers ready for a lifestyle flex.
Materials & Innovation
What makes the Nike Alphafly NEXT% stand out is the technological layering—each material choice serves a function, and together they create a performance monster.
Material Breakdown:
- Upper: Atomknit (a stretched, steamed Flyknit variant) for breathability and lockdown
- Midsole: Dual-density ZoomX foam with full-length carbon fiber plate
- Cushioning: Two massive Zoom Air pods under the forefoot
- Outsole: Lightweight rubber with targeted traction zones
Every component is chosen for race-day performance, from energy return to weight reduction.

Comfort & Performance
The Alphafly NEXT% is designed to help you run faster, longer. While some elite shoes sacrifice comfort for performance, this model manages to deliver both.
Comfort Features:
- ZoomX foam delivers unmatched energy return and cushioning
- Carbon fiber plate improves stride efficiency and propulsion
- Zoom Air units add bounce to toe-offs
- Wide forefoot provides surprising stability at high speeds
- Atomknit upper hugs the foot without suffocation
It feels weird at first—but after 5 minutes, you realize it’s not just a running shoe; it’s a weapon.
Fit & Sizing
The Alphafly NEXT% fits true to size for most runners, but its unique construction and performance-oriented design mean it won’t feel like your average pair of Nike shoes.
Fit Notes:
- Narrow heel lock-in for less slipping
- Roomy toe box for swelling on long runs
- Lightweight feel but with structure
- Minimal internal padding—it’s built for speed, not plush comfort
Ideal for serious runners or sneaker fans who want to experience Nike’s highest level of design.
Who Should Wear the Alphafly NEXT%?
While originally designed for elite marathoners, the Alphafly NEXT% has also become a cult favorite among:
- Competitive distance runners
- Sneaker collectors looking for tech-forward designs
- Athletes training for half or full marathons
- Style-forward wearers wanting a unique silhouette and colorway
Though it’s not a daily trainer, its look and engineering make it a coveted piece in any serious sneaker rotation.
