AN ELEMENT OF SURPRISE. Updated with a python-print upper, the Nike React Element 55 borrows design lines from heritage runners like the Nike Internationalist and then places it all on Nike React technology. A lightweight textile and synthetic leather upper provides durability. Nike React technology delivers an extremely smooth ride. Rubber pods on the midsole and outsole provide durable traction. Eyestay foxing follows the wavy design lines of the eyestays of the Nike Internationalist. A heel clip provides a stable feel. A pull tab at the heel makes it easy to put on and take off. "
