Adventure awaits with this trail shoe, ready to accompany you on rough surfaces! Midsole The midsole is made of ReactX foam. Compared to Nike React foam, ReactX is designed to reduce the carbon footprint of a pair of midsoles by at least 43% due to the reduced energy in the manufacturing process, and to increase energy efficiency by 13%. Upper Flywire technology replaces laces with high-tensile wires that act like suspension bridge cables and provide precise support.
