As planned, Inov-8 presented a new ultratrail running shoe that is the first one to use graphene in midsole, after testing various mixes with high-tech polymers over a total distance of 18,000 km. The English brand claims that its graphene-enhanced midsole offers 25 percent more energy return than an industry-standard EVA midsole, plus more comfort and durability. Its new Trailfly Ultra G 300 Max shoe features three patent-pending technologies developed in collaboration with the University of Manchester, which sealed an exclusive partnership with the company in 2016 after studying the properties and uses of graphene since 2014. In addition to the graphene-enhanced rubber outsole of the G Series launched by the company in 2018, the patents cover the G-Fly foam of the midsole and an Adapter Flex construction that allows the ankle to stay straight on uneven terrain. The shoe can be ordered from Apr. 8 for £170 or €190 or $195 per pair.
