Highlights
- Helion HF Midsole The Helion HF hyper foam midsole cranks up maximum energy return and rebound, giving you that responsive ride with a kick on every stride. It's low cushioning at 6mm drop, perfect for speed work where you need bounce without bulk. Ultralight at 278g, it keeps you nimble for intervals or races, transforming training into something propulsive and alive. Feel the difference as it absorbs impact then explodes back, supporting neutral runners who demand more from their miles.
- Nylon-Blend Speedboard Infused with glass fiber, this revised nylon-blend Speedboard drives powerful forward propulsion and a fast, rolling sensation. It works with the extreme rocker shape for springy transitions, making toe-offs feel effortless and aggressive. Built for high-speed sessions, it channels race-shoe energy into your daily grind, so you're not just running - you're surging ahead with purpose.
- Engineered Woven Mesh Upper Ultralight and breathable, the woven mesh upper lets your feet stay cool and fast during intense pushes. Updated toebox adds forefoot space for comfort at pace, with large logo and grip pads on the toe box nodding to elite racing aesthetics. Reflective elements boost visibility too, keeping you safe while you chase those splits.
