Superlight Running Shoes
Superlight sneakers with a firm midsole can help you run faster.
Winner: LunarEclipse+ 2, $135; Nike.com. A sock liner with two densities of foam cradles your midfoot. Have high arches? These will fit like a glove. And even with all of the bells and whistles, testers found the shoes surprisingly "airy and flexible."
Runner-up: Single-Track Hayasa, $110; TheNorthFace.com. "So light!" testers agreed. Pro racer Tsuyoshi Kaburaki codeveloped this 7.2-oz featherweight (the name means "speed" in Japanese). The grippy sole acts like cleats? but with enough padding to feel smooth.
Editor's pick: Triumph 9, $130; Saucony.com. "I trained for a 5K in these, and the springy platform helped me shave two minutes off my time." —Marissa Stephenson, fitness editor.
