Built for confident speed, this shoe is for trail runners looking to move fast and maximize efficiency. The rockered shape of the midsole propels you from foot strike to toe-off, while an ultra-responsive supercritical foam compound maximizes energy return and reduces fatigue—helping you stay in PR mode all day long. A carbon-fibre plate adds extra stability so you can let it rip on uneven terrain with confidence, and outsole lugs provide solid trail traction and kick off excess dirt.
