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