Free your run and take the time to really feel the terrain by slipping into the PureConnect®. Part of the PureProject™ Collection from Brooks®. Recently awarded "Best Debut" in the winter 2012 Shoe Guide of Runner's World magazine. Brooks developed five unique features called the Ideal Technologies (Nav Band, Toe Flex, BioMOGO DNA, Ideal Heel and Anatomical Last) that are featured in every PureProject shoe. Combined, these technologies are designed to promote an efficient, natural stride by encouraging a more forward foot strike, which places the runner over their center of gravity, helps align the body and reduces harmful stress. The lightest shoe in the collection. Built for the neutral runner seeking a minimalist running shoe that places little between the runner and the ground. Highly breathable open mesh upper. Ultralightweight synthetic overlays provide light structural support. Elastic Nav Band wraps across the instep for a secure, glove-like fit. Lightly padded tongue and contoured heel cup for added comfort. Lightweight foam insole offers light underfoot plush. BioMoGo DNA is a blend of earth-friendly BioMoGo and responsive Brooks DNA, and has a gender-friendly cushioning design, making for a dynamic ride. Midsole Offset: 4mm. Extended Toe Flex - The split-toe feature augments forefoot flexibility and promotes the big toe to engage the runner's natural stability and power during push-off. Ideal Heel - The heel is slimmed down to encourage contact points to shift forward, aligning the joints and creating optimal energy return. Built on an anatomical last, the shoe's shape contours to your foot, promoting support and a glove-like fit. Measurements: Heel Height: 1 in. Weight: 6 oz. Heel Height: 1 in. Weight: 6 oz.
