What Our Gearhead® Experts Are Saying:"I took this on steep, loose terrain where I'd normally be white-knuckling every descent, and the Vibram MegaGrip outsole held without hesitation. The roomier forefoot and improved ankle cuff kept my foot locked in place in a way earlier versions of this shoe never managed."Why We Like ItThe dual-layer midsole stacks ZoomX foam over Cushlon 3. 0. The ZoomX delivers the cushioning and rebound, while the Cushlon layer provides the density and stability that ZoomX alone can't hold on uneven trail surfaces. Nike widened the last and reworked the upper construction for this version, adding a semi-bootie construction, midfoot support wings, and a cushioned heel counter that together deliver the lockdown the shoe previously lacked. The Vibram MegaGrip outsole with Traction Lug technology handles conditions from hard-packed singletrack to wet rock and mud.
