The perfect choice for runners just starting out, the Electrify NITRO 2 from Puma delivers the cushioning and reliability needed your daily jog. The dual midsole contains a lightweight, nitrogen-injected NITRO foam in the heel alongside a sturdier PROFOAMLITE throughout the rest of the midsole, allowing for an airy, cushioned ride. The breathable mesh upper has been revamped with a futuristic look and the rest of the shoe has been retooled with a rolled collar, built-in heel lock, and a special ‘cat’s’ tongue to secure the heel for every run.
