•Air mesh and synthetic nubuck upper for breathability and long wear •Lace-up closure with molded sockliner for perfect fit •Rubber outsole with EverRide and EverTrack components for superior traction, durability and advanced cushioning •Innovative midsole with BioRide technology, featuring three components that work together to create a naturally responsive ride: •1. Rocker: Incorporates a rocker shape for a centered heel strike and effortless toe-off. •2. Flex: Most sidewalls are raised to stabilize the foot but then restrict the flex. Our solution? We incorporated flex grooves in zones where it makes biomechanical sense to allow the foot to move naturally. •3. Groove: A groove on the side of the shoe gives the foot a feel for the ground, giving you a more responsive ride. This style is eligible for the PUMA Time Trial Program.
