THE SELL: Low weight, full throttle—with a one-piece upper and seamless overlays for longer-run comfort. THE TEST: The Infinitis were among the most agile and fleet trail runners in our test, thanks to a tacky Vibram waffle, a noticeably narrow fit, and heat-sealed (instead of stitched) overlays, which boost the sturdiness of the one-piece upper. “The first thing I noticed,” said a tester, “was how light they are. They really seemed to energize my run.” Good rock protection? Check. Water resistance? Yup. Comfort? The seamless interior gave hot spots the boot. THE VERDICT: Quick, impressively light, and well cushioned, the Infinitis know only one speed—faster. Wider feet, you might find the fit a bit tight. 10.6 oz.
