Nike Women's Wmns Free 3.0 V5 PRM, WHITE/BLACK, 6.5 M US

In 2002, three of Nike's top researchers analyzed a group of people with pressure-measuring insoles and high-speed cameras when the foot was in motion. After eight years of studying, they've created the most flexible and conventional shoes to-date. Meet the latest edition, the Nike Free 3.0 v5 EXT Running Shoes. With Flywire cables for an adaptive fit, flex grooves on the outsole for flexibility and traction, and fused phylite for an ultra-smooth, frictionless stride, it's true that these running shoes have the next-level comfort and adaptiveness to keep you going.
