Free RN Distance 2 'Boston Marathon'

This Nike Free RN Distance 2 is a special edition colorway created for the 2017 Boston Marathon. Weighing in at 8.8 oz with a 4mm heel-to-toe offset, the performance runner features a free-floating, internal mesh bootie and Flywire cables for a lockdown fit. A loosely woven fabric in the forefoot flex zone offers natural stretch, and no-sew overlays on the heel provide lightweight support. The shoe’s cushioning system features a re-engineered Lunarlon foam fused to a lightweight IU carrier for soft cushioning and a smooth transition. An Auxetic tri-star patterned outsole comes with six different flex points designed for natural motion and multi-surface traction.
