Engineered to outpace the demands of urban running, this sock-fit sneaker sports a ribbed lacing cage that locks comfortably to the springy Helion™ foam sole. Responsive Speedboard construction moves naturally with your foot to transform every heel strike into an explosive toe-off, with durable, high-abrasion rubber in the tread providing superior grip on urban streets, sidewalks and steps—even when they're wet.
