Style meets performance in the Nike 4307 eyeglasses for women and men. These rectangular full-rim frames feature an enhanced browline for a bolder look around the eye that creates a distinctive contour to the face. Known for implementing performance materials worthy of sports equipment, Nike constructs these frames in Flexon, a corrosion-resistant alloy that returns to its original shape after bending or twisting. A discreet Swoosh at the temple brow end adds sporty appeal. Designed for the active trendsetter, these ergonomic frames from NIke are a slam dunk.
