adidas moves forward with the groundbreaking momentum of BOOST by introducing the Cosmic BOOST. Taking design features directly from the Ultra BOOST hero design, the Cosmic features a further refined lightweight upper and fit. Utilising an engineered mesh toe and quarter, the weave features the three stripes on the saddle and different densities in the forefoot for stretch, support and breathability. Flat lock seams connect to a neoprene heel and collar for a silky fit. Supported by an updated and upgraded Midsole with a bare BOOST forefoot and an encapsulated BOOST heel, the Cosmic uses adidas' climachillâ„¢ technology and perforations for optimal ventilation - perfect for warmer conditions.
