Nike Free RN Flyknit 2018 - White - UK 9

While comfortable for everyday training, the Nike Free RN Flyknit 2018 is designed for a natural feel and may not offer sufficient cushioning or support for the demands of marathon running for all individuals. They are better suited for shorter to medium distances or speed work.

You can spot clean the Flyknit upper with a soft brush, mild soap, and cold water. Avoid machine washing or high heat drying.

The Free RN sole is designed with deep flex grooves to mimic the natural motion of your foot, providing flexible cushioning and a more grounded, barefoot-like feel.

These shoes are designed for a natural feel. If more cushioning is needed for longer distances, consider using them for shorter runs or speed work, and opt for a shoe with more midsole foam for marathon training.

Minor snags can sometimes be carefully trimmed with small scissors, but significant tears may compromise the shoe's integrity. Avoid contact with sharp objects.
