PWRRUN PB offers lightweight, springy shock dampening for comfort and performance, contributing to personal bests. This foam is 40% lighter than previous PWRRUN predecessors, allowing for faster and steadier running. Sandwiched between two layers of PWRRUN PB Foam is a carbon-fibre plate, which, combined with SPEEDROLL technology, creates powerful transitions and propels you forward effortlessly for a more dynamic run. PWRRUN HG foam on top provides additional lightweight and springy cushioning with more rebound than previous PWRRUN foams. The XT-900 outsole, made of carbon rubber, offers control on the track and pavement. It provides a solid connection with the ground for efficient push-offs. The chevron tread pattern enhances traction on wet surfaces and compact dirt while allowing the sole to flex for fluid movement. Reinforced high-abrasion zones ensure optimal traction and durability.
