Free RN 2017 'Black Anthracite'

Developed for interval training and long-distance runs, the Nike Free RN 2017 follows its predecessor in a flexible design. This 'Black Anthracite' variant incorporates a circular seamless mesh upper with reinforced zones, a tongue integrated into the internal bootie and Flywire cables attached to the sole unit. The dual-layer midsole expands and contracts upon ground-strike, flexing naturally due in part to a tri-star outsole.
