Nike created the React foam technology specifically with the needs of runners in mind. Through the use of heat mapping technology, Swoosh designers were able to identify the areas where athletes required the most cushioning, ensuring a high-impact stride was thought out. Building upon the triumph of React foam, Nike has gone on to combine it with other cutting-edge innovations. The Wmns Odyssey React 2 Flyknit 'Ember Glow' model seamlessly merges the React sole with a Flyknit upper, resulting in a multi-purpose shoe ideal for both road running and gym workouts.
