Puma Fast-RB Nitro Elite

The PUMA Fast-RB Nitro Elite features a smooth looking upper made from engineered mesh with targeted reinforcement from PWRTAPE to lock in your fit and improve durability. It also features a padded collar to enhance your comfort. But the big story is that crazy looking midsole. First off, the stack height, at 58 - 46mm this is seriously beyond the legal limits (40mm) for racing in world athletics competitions, which may be why the RB in the name stands for rule breaker. It also features an illegal number of plates, with one running under the foot and another two acting like flat, or leaf springs helping to provide that incredible bounce. The construction of the foam is also unique, using different densities of their pinnacle Nitro Elite foam for a lightweight, energised feel that adds to the bounce factor in every stride. Underneath PUMAGRIP rubber provides excellent traction in a durable package to ensure you can make the most out of every run in these tech forward, innovative and unique running shoes.
