The Nike Free RN 2018 'Black' refreshes the running staple with adaptive technology and a streamlined design. This edition features a circular-knit upper that conforms to the foot, utilizing Flywire cables integrated with the laces for dynamic support. A specialized heel counter system enhances stability, while reflective details improve visibility in low-light conditions. The chassis is built on a co-molded foam midsole for lightweight cushioning, paired with a tri-star patterned outsole that expands and contracts to allow natural motion. Finished in a classic black and white scheme, this model offers a versatile option for daily wear.
