The adidas Pure Boost 2017 features a versatile, agile and adaptive design to enable runners to endure anything the city environment has to offer. New features of this Pure Boost include an 8mm heel lift and progressive sculpting of the BOOST midsole, with a wider forefront for optimum support. The outsole is also built for the specific requirements of street running, with the rubber extended on the medial side for additional support. The stretch web design provides superior grip, while allowing the foot to work in harmony with the BOOST midsole. Meanwhile a new knit upper incorporates a highly adaptive upper that moves with the runner’s gait. A new double wrap tongue construction provides support but also allows the foot to move in harmony with the upper.
