Best for Comfort and Speed

If you're getting serious about running and looking for a lighter shoe, start by trying this on. Our test-runners were wowed by the way this shoe's one-piece, lattice-knit upper provides a glove-like fit (and reduces the shoe's weight). They also loved how its foam sole provides an ideal balance between cushioning and support. (8.5 oz; 10mm drop) [$150; nike.com]
