The new One 2.5 is built for speed, without sacrificing the comfort needed to maintain it through the finish line. A FootShape toe box lets your toes relax and move freely for incredible comfort, extra stability and a more powerful toe-off. Innerflex technology adapts to the flexion of your foot with omnidirectional flex grooves in the midsole. Responsive A-Bound cushioning protects the feet at impact and rebounds to add a spring to each step. The weight-balanced, Zero Drop platform helps you maintain low-impact form, even when fatigue sets in at the end of a hard race or workout. Go fast, go hard and stay comfortable from step one to the finish line with the new One 2.5. WHAT'S NEW: Improved Fit, Redesigned Upper, New Color Options.
