This shoe just looks fast, and that's just what it's made for. Brooks has developed DNA FLASH, their nitrogen infused DNA foam unlike any combination of lightweight and responsive cushion they've developed up to this point. A no-nonsense woven upper conforms nicely to the foot during all of your training, speedwork, racing and everything in between. With the durability to go the distance and the weight and energy return to challenge some segment crowns on Strava, Brooks has written the newest path to the most fun you've had running in some time.
