An instant favorite among runners since version 2, the Endorphin Speed took the running world by storm by incorporating elements you’d find in a racing shoe into a well-cushioned trainer.\n\nPWRRUN PB can be found throughout the midsole, made with a lightweight and super responsive PEBA foam that makes an uptempo run feel a bit easier. Embedded within this foam you’ll find a winged nylon plate that adds some extra pop and propulsion to each step. Saucony’s SpeedRoll Technology uses rocker-shaped geometry that encourages you forward, making for a more uptempo run.\n\nUp top, the Endorphin Speed 5 uses an engineered mesh material that feels lightweight and fits comfortable around the foot. It also helps increase breathability to keep your feet stay cooler in warmer weather. On the bottom you’ll find a new, optimized outsole design with increased coverage to boost durability and help create smoother transitions.\n\nRead More: The Saucony Endorphin Speed 5\n\n7 Best Tempo
