Nike React Infinity Run Flyknit 2 - Silver - Orange - Trainers - UK 8.5

Yes, the React Infinity Run Flyknit 2 is designed for comfort and durability, making it a suitable option for marathon training and racing for many runners.

You should have about a thumb's width of space between your longest toe and the end of the shoe. The shoe should feel snug but not tight, with no slipping at the heel.

It is not recommended to machine wash these trainers as it can damage the materials and cushioning. Hand washing is the preferred method.

The React Infinity Run Flyknit 2 specifically focuses on providing maximum cushioning and a smooth, stable ride using Nike's React foam technology, combined with the adaptive Flyknit upper for a secure fit.

Nike React foam is known for its durability and resistance to compression, meaning it should maintain its cushioning properties over a significant number of miles.

The Flyknit upper offers some adaptability, but the shoe is designed with a standard width. If you have particularly wide feet, you may want to try them on to assess the fit or consider models known for wider options.

Ensure you have the correct size. Try wearing them with moisture-wicking running socks. Break them in gradually with shorter runs before attempting longer distances.

While the rubber outsole offers good grip, extremely wet or slippery conditions may reduce traction. Exercise caution and consider alternative footwear for such conditions if needed.

Carefully try to smooth out the snag. Small snags may not affect performance, but significant tears can compromise the shoe's structure and fit. Avoid contact with sharp objects.
