The Nike Epic React Flyknit deserves the hype as this runner is about as innovative as it gets. That chunky midsole is 13% bouncier than the LunarEpic and way more durable too. Nike tested the shoe by giving a pair to world class athletes in order to get their opinion. But unbeknown to those athletes, Nike had given them trainers which had already racked up over 500 miles. When asked what they thought, most of the runners were shocked to find out that they weren’t brand new.
