Polo Ralph Lauren Big Pony Socks - 3 Pack - Blanco

This is the most advanced Endorphin Pro we've ever engineered. It is built to deliver a return on investment you can feel with every stride.

At its core is a new dual-density engine: a high-performance fusion of PWRRUN PB and Super Critical PWRRUN HG for elite energy return. We've paired this with a re-engineered slotted carbon plate that optimizes SPEEDROLL technology, offering a smoother transition and an explosive snap off the pavement. Finished with a targeted PWRTRAC outsole for unwavering grip, the Pro 5 is the definitive edge you need to shatter your personal best.
