This shoe packs in technology like a NASA experiment, delivering the year’s fastest and most comfortable ride. Independent gel units in the rear foot absorb impact by adapting to individual strides; the midsole material, called Solyte, is about half the weight of ASICS’s standard-density EVA; and the new polyester upper material—Spacemaster-UV—stretches for a precise fit. 11 oz; www.asicsamerica.com
Bonus: Access your inner disco ball with a glut of reflective material.
Bummer: Technology ain’t cheap.
