The Puma ELECTIFY NITRO is a progressive design that works great for all runners and any distance, especially for those just getting started. The two-part midsole offers NITRO FOAM in the heel and the more durable PROFOAMLITE throughout the rest of the midsole. This shoe remains light for the amount of cushion offered, and PUMAGRIP enhances safety in the outsole rubber that is 51% more grippy than rubber from the SPEED line. A dual-color engineered mesh upper looks futuristic and offers great breathability. The ELECTRIFY NITRO is the perfect choice for the new runner looking for great cushion and value.
