Nike React Infinity Run Flyknit 3 - Black - UK 5

Yes, the React Infinity Run Flyknit 3 is designed with ample cushioning and support, making it suitable for marathon training and race day for many runners.

The Flyknit material is engineered to be breathable and stretchy, conforming to your foot's shape for a personalized, sock-like fit that moves with you.

While comfortable, these shoes are primarily optimized for forward motion in running. For gym workouts with varied lateral movements, dedicated training shoes might offer better stability.

You should have about a thumb's width of space between your longest toe and the end of the shoe. The fit should be snug but not constricting, with no heel slippage.

React technology provides a soft, responsive, and lightweight cushioning that absorbs impact and returns energy, leading to a smoother and more comfortable ride.

The Flyknit upper offers some water resistance but is not fully waterproof. They are best suited for dry or lightly wet conditions.

Ensure laces are loosened before putting on. If still too tight, consider trying a half-size up or check for swelling after longer runs.

React foam is designed for durability, but cushioning may gradually decrease with extensive mileage. Check for wear on the outsole, which can indicate it's time for a new pair.

Ensure the outsole is clean and dry. If the issue persists on wet surfaces, consider the limitations of the shoe's traction in such conditions.
