Nike Flexon frames are made of a durable patented metal alloy.

Unlike conventional metal frames, Nike Flexon frames are nearly impossible to twist out of shape and are resistant to metal fatigue.

Flexon frames are perfect for the wearer that appreciates and requires performance; such as athletes and children that are rough with their glasses.
