Multi surface tread geometry balances grip and flexibility

A PROPULSIVE SPEED-TRAINING PARTNER

Bolder than ever before, the Mach X 2 brings the heat to speedwork. Inspired by the Cielo X1s race-ready geometry, we combined an extra-resilient PEBA-topped midsole and increased rocker profile for an aggressive toe-off, then extended the Pebax plate design for enhanced support and propulsion. With an extra-breathable and supportive woven upper and a sleeker collar, this speed trainer keeps things light, cool, and fast for next-level efforts.
