The Nike React Infinity Run Flyknit 2 Herren (men's) is a significant iteration in Nike's ongoing pursuit of creating supremely comfortable and injury-preventing running shoes. Building upon the success of its predecessor, the Infinity Run Flyknit, the second generation refines the design and enhances performance in several key areas. This in-depth review will delve into the specifics of this model, comparing it to similar Nike offerings like the React Phantom Run Flyknit 2, and addressing common queries found online regarding the Nike React Flyknit 2 line, including different colorways like the Nike React Flyknit 2 black (ct2357-007), and exploring the future with the react infinity run Flyknit 4. We'll also touch upon the women's version, Nike React Infinity 2 women, to highlight gender-specific differences.
Design and Construction:
The Nike React Infinity Run Flyknit 2 Herren boasts a sleek, modern design. The upper, constructed primarily from Flyknit, offers a breathable and adaptive fit. Flyknit's inherent flexibility allows for a sock-like feel, conforming to the shape of the foot without excessive constriction. This is particularly beneficial for runners who prefer a snug, secure fit without compromising comfort. The Flyknit material itself is strategically engineered with varying densities, providing targeted support where needed, particularly in the midfoot and heel areas. This zonal support is a key improvement over the original Infinity Run, offering better stability and preventing excessive foot movement within the shoe.
The midsole is where the magic happens. Nike's React foam technology, known for its exceptional cushioning and responsiveness, forms the core of the Infinity Run Flyknit 2. The foam's unique composition offers a balance of softness and firmness, providing ample shock absorption without sacrificing energy return. The wider, rockered geometry of the midsole is a defining feature. This design promotes a smoother, more efficient gait cycle, encouraging a more natural and less jarring stride. This is especially beneficial for runners prone to injuries like plantar fasciitis or runner's knee, as it minimizes impact forces on the joints.
The outsole incorporates a durable rubber compound strategically placed in high-wear zones. This placement optimizes traction without adding unnecessary weight, contributing to the shoe's overall lightness and agility. The pattern of the outsole is designed for versatility, performing well on a variety of surfaces, from roads and pavements to lightly trafficked trails.
Performance and Feel:
The Nike React Infinity Run Flyknit 2 Herren provides a uniquely comfortable and responsive running experience. The combination of the Flyknit upper and React foam midsole creates a cushioned yet energized feeling with each stride. The rockered geometry noticeably reduces impact, making it an excellent choice for long runs and runners who prioritize comfort. Many users report a significant reduction in post-run fatigue and muscle soreness compared to other running shoes.
The shoe's stability is noteworthy. While not explicitly designed as a stability shoe, the wider base and supportive midfoot structure effectively prevent excessive pronation or supination, making it suitable for a wide range of foot types and running styles. The responsive nature of the React foam promotes a smooth, efficient stride, contributing to improved running economy and reduced energy expenditure.
The breathability of the Flyknit upper is also a significant advantage, particularly during warmer weather conditions. The airflow keeps the feet cool and dry, preventing overheating and discomfort. However, it's worth noting that, while breathable, the Flyknit 2 isn't explicitly designed for cold weather running. For colder conditions, runners may want to consider alternative options or use thicker socks. This is a point of contrast with some other winter-specific running shoes.
