B E L I E V E In The Run on Instagram: "Behind the scenes at the start of Chasing 100, where @alfredo.mejiaa is witnessing a bold challenge that sees five Adidas athletes attempt to run the fastest ever 100K at the unique Nardò Ring in Lecce, Italy. On their feet is the Adidas Adizero Evo Prime X, an all-new super shoe featuring almost 50 mm of stack height and weighing only 4.7 oz. (136 g) for a US M8."
