Overview
The Nike React Infinity Run Flyknit 3 is engineered to keep runners moving mile after mile with a soft but stable ride. Featuring a plush React foam midsole and a rockered geometry, it is best suited for easy runs and long distances rather than speedwork. Its wide base and evolved Flyknit upper offer improved stability and breathability, continuing the legacy of its predecessors while introducing meaningful upgrades.
The Infinity Run Flyknit series is known for its durability, ample cushioning, and support mechanics—all essential for high-mileage runners and those looking for a comfortable training shoe.
Key Features
- High-rise React foam cushioning for close-to-foot responsiveness and plushness.
- Wider outsole base delivering increased stability at ground contact.
- Full-length rubber outsole providing reliable traction and durability on urban terrain.
- Upgraded Flyknit upper with targeted zones for breathability, flexibility, and containment.
- Flywire cables in the midfoot enhancing lockdown and foot security.
- Hybrid tongue construction blending sock-like comfort with adjustability.
- Padded collar and heel for extra comfort and support around the ankle.
- Heel clip and flare for rearfoot guidance and mild stability.
Design and Materials
The Nike React Infinity Run Flyknit 3’s design reflects feedback from athletes and casual runners alike:
- Flyknit Upper: Nike’s proprietary Flyknit material wraps the foot with a lightweight, secure fit. Breathability zones and flexible panels adjust with the wearer, while midfoot Flywire cables provide enhanced containment for a stable feel.
- React Foam Midsole: This full-length cushioning system is firmer and more supportive than softer foams like Nike’s ZoomX, offering a snappy yet protective ride. It tends to require a break-in period, softening and becoming more responsive with use.
- Outsole: The rubber outsole is designed for maximum grip on roads, with a pattern that ensures traction even in wet conditions. While not intended for technical trails, it can manage well-groomed paths and everyday urban surfaces.
- Padded Collar and Heel: Extra cushioning is added around the heel and ankle to prevent discomfort and support the rearfoot, making the shoe comfortable straight from the box.
Performance Review
The Nike React Infinity Run Flyknit 3 is classified as a daily mileage or recovery shoe, excelling in scenarios where comfort and protection outweigh speed or agility. Here’s how expert reviewers assessed its performance:
- Easy, Long Runs: The shoe’s plush cushioning and smooth rockered transitions make it ideal for extended sessions on paved surfaces. The React foam is protective and gentle on the joints, particularly after it molds to the foot with repeated use.
- Ride Quality: The shoe provides a rockered ride with heel bevel and toe spring, resulting in smooth transitions and effortless momentum. Once broken in, the foam delivers a soft and slightly bouncy feel, but without the excessive squish found in ultra-soft trainers.
- Weight and Responsiveness: While heavier than performance trainers, the Infinity Flyknit 3’s construction is geared toward comfort rather than speed—making it less suitable for interval training or sprints.
Stability and Support
Although technically classified as a neutral shoe, the Infinity Run Flyknit 3 incorporates several features to guide and support the foot, especially in the rearfoot area:
- Mild Stability: The heel clip, outsole flare, and rocker geometry work together to deliver rearfoot guidance, helping to center the ride and reduce excessive inward or outward motion.
- Forefoot Stability: A wide base and pronounced flare at the front of the shoe enhance ground contact and forward rolling, keeping movement smooth and efficient.
Despite these elements, the shoe is not recommended for those needing high arch or midfoot stability; runners with neutral mechanics or mild rearfoot stability requirements will benefit most.
Durability and Traction
Durability is a key selling point of the React Infinity Run Flyknit 3:
- High-mileage outsole: The thick rubber sole shows minimal wear even after dozens of miles, ensuring longevity and consistent grip.
- Traction: The shoe performs exceptionally well on wet and dry urban surfaces, including concrete, treadmill, and lightly groomed trails. It is not designed for technical or rough off-road terrain.
Sizing and Fit
- Fit: Reviewers note a snug, sock-like fit, particularly in the forefoot, thanks to the integrated tongue and full knit upper. The toebox is wider for greater stability, accommodating different foot shapes.
- Recommendations: Due to the plush midsole and overall fit, going a half-size up may be advisable for those planning longer runs or expecting foot swelling.
- Break-in Period: Multiple reviewers report a significant break-in phase, with the arch and heel clip softening and molding to the foot after several uses, resulting in a custom fit that enhances comfort and support.
