The Free RN 5.0 'Obsidian Mist' is designed with a bootie construction and anatomical fit to provide a natural feel during low-mileage runs. Released in May 2019, this iteration comes with a neutral colorway highlighted by hits of blue, yellow, red and a green lining. The slip-on fit is accomplished with a stretch collar turned out in back to protect the Achilles. For the barefoot-like feel that defines the Nike Free collection, this sneaker features deep sipes in the foam midsole/outsole.
