The Puma ELECTIFY NITRO 3 has an advanced design that is suitable for all runners and any distance, especially younger runners or those just starting out. The two-piece midsole is redesigned in our 3rd model to allow for more NITRO in the heel and durable PROFOAMLITE in the rest of the midsole. More NITRO means better responsiveness and grip underfoot. The shoe remains lightweight for the cushioning provided and PUMAGRIP improves safety in the outsole, which is 32% more grippy than the SPEED line. The mesh upper looks futuristic and offers high breathability. A rolled collar with plenty of padding secures the heel and provides a comfortable and secure fit. The ELECTRIFY NITRO 3 is the perfect choice for new runners looking for good cushioning and value.
