Lighten your step. The Men’s Nike Free RN 2017 Running Shoe brings you miles of comfort in an updated version with reduced layers and weight. A breathable circular-knit upper and a tri-star outsole pattern adjust to your foot’s every step, delivering support and flexibility.
Updated, circular-knit upper supports with an improved 1:1 fit. Low-profile cushioning and rounded heel encourage natural footstrike. Auxetic tri-star outsole pattern expands with your step for flexible cushioning. Dynamic Fit technology is achieved through Flywire cables integrated with the laces for an adaptive, supportive fit. Minimal, molded sockliner mimics the curvature of the foot to add support. Segments of solid rubber under the toe and heel enhance traction and durability in these key wear zones.
Nike Free is all about speed. But first you'll need to build your muscles, because Nike Free takes some getting used to. Deep cuts in the outsole mean your feet flex and move the way they would if you were barefoot.
Dynamic Fit technology features soft material that wraps like fingers around the midfoot and arch for a glove-like fit. Runners can customize their fit by tightening the laces, which are connected to the Dynamic Fit midfoot cage.
Flywire helps provide ultra-lightweight support and comfort for your foot. It gets its strength from thin Nylon fibers strategically placed on the upper of the shoe to hold the foot in place, helping to reduce slippage during activity. This allows for a massive reduction in weight because material is used only where it’s needed for structure.
