The Nike iSPA OverReact Flyknit collection expands with the "Light Bone" colorway. This iteration features a laceless woven FlyKnit upper accented by blue, red and yellow. Adding to the patchwork aesthetic are the lock-down Velcro clip and tear-away tongue tags. Underfoot, a textured React Foam midsole comes with 3M reflective detailing to make sure you stand out even in the dark.
