Building upon the groundbreaking innovation spearheaded by Nike designers Eric Avar and Tobie Hatfield back in 2004, the Free RN 2017 'Obsidian' has emerged, offering an unparalleled experience of a truly unencumbered and flexible run while concurrently presenting a myriad of additional advantages. By seamlessly incorporating Flywire technology into the laces and integrating a single-piece, seamless knit upper comprised of varying mesh gauges, this shoe transcends to provide exceptional stability and breathability, rendering it ideal for both invigorating runs and rigorous workouts. What's more, this shoe boasts an astonishingly lightweight construction, granting it universal appeal and making it an excellent everyday companion even for those who may not necessarily be avid runners.
