The Invincible Run is the shoe runners who are passionate about Nike technologies have long wanted: a 100% ZoomX midsole. The Nike ZoomX Invincible Run offers high cushioning and high energy return. With such a soft midsole the logic would be a very unstable shoe, right? To combat instability, Nike made two reinforcements, in the forefoot and buttress area, creating a wider base.
The Flyknit textile upper is soft with a little stretch. The reinforced tongue has plenty of foam, making it softer and more comfortable, without sliding sideways. The heel counter with plenty of foam in the heel is very comfortable and does a great job providing good stability. Also, in the front (toe box) there is a good space for the toes to spread out.
