About the shoe
The Nike React Infinity Flyknit 2 is a plush, max-cushioned daily trainer designed to keep runners comfortable and supported over high mileage. With a secure, upgraded upper and a smooth, rolling ride, it excels at easy and long runs, though its high stack may feel less stable on sharp turns. This shoe is a strong choice for runners seeking injury prevention and all-day comfort.
Reviewers consistently note robust build quality, with the outsole and midsole holding up well over high mileage (400-500 miles reported by some testers). Minor concerns exist about upper wear and React foam compression over time, but overall longevity is above average for the category.

The Nike React Infinity Flyknit 2 is widely regarded by experts and users as an outstanding daily trainer due to its plush React foam cushioning, mild stability features, and comfortable upper. It excels for easy and moderate-paced daily mileage, offering a smooth, protective ride that reduces fatigue on repetitive runs. Its deep cushioning and wide base make it suitable for long runs, with reviewers noting comfort even beyond 30 km, though some mention instability on sharp turns due to the high stack height. For tempo runs, the shoe can handle moderate uptempo efforts, but its weight and lack of snappy responsiveness make it less ideal for sustained threshold or interval work. For racing, especially at 5K to marathon distances, it is generally considered too heavy and not propulsive enough compared to dedicated race shoes. The outsole and upper are not designed for trail use, offering limited traction and stability off-road. For recovery runs, the soft, stable ride and forgiving cushioning make it a top choice for easy, post-workout mileage.
- Exceptionally soft and protective cushioning makes long runs and recovery days noticeably more comfortable for most runners
- Improved upper with Flywire integration and enhanced heel padding delivers a secure, blister-free fit compared to the previous version
- Smooth rocker geometry encourages a natural forward roll, reducing fatigue on easy and moderate-paced runs
- High stack height can feel unstable on sharp turns or uneven terrain, especially for runners needing strong lateral support
- Lacks the energetic 'pop' of true speed-oriented shoes, making it less ideal for fast intervals or race-day efforts
