More speed, more comfort. Puma's fastest running shoe to date is infused with pinnacle performance features while maintaining a super light weight. The new NETFIT cage allows you to customise your fit by lacing whichever way best suits your foot type for a more secure and comfortable fit. The dual-layer midsole infused with IGNITE provides longer lasting cushioning and responsiveness. The engineered forefoot Propulsion Zone in the outsole propels you forwards, providing a powerful, snappy toe-off that increases stride length and speed.
