Nike's much-hyped re-release of its '90s ACG Skarn hiking sneaker sports the same swooping, aerodynamic curves of its sneakerhead-favorite Air Max 97. Twin lines of sturdy roping anchor the laces and follow the contours of the upper, with layers of color and texture popping all over the sculpted exaggerations of the sole. It sits on the signature wide base and super-lugged tread that gives it stability on the trails and in your everyday sneaker rotation.
