The Odyssey React is a shoe that will accompany you through whatever challenges you want to conquer. Nike’s React foam is designed to be lightweight, yet extremely reactive to each step while returning energy to you. This will keep your feet feeling fresh after even your longest runs. If you have wider feet, you might want to size up for a more comfortable fit. These shoes have a medial heel plate helps prevent the dangerous inward rolling of your ankles. If you have flat feet, this shoe has what you need to just do it!
