Coming off of the heels of the overwhelming success of version 1. Nike makes only the small necessary tweaks to push it even closer to perfection. Keeping everything that made it successful in the midsole and outsole. the Infinity 2 stabilizes the foot and body through the gait process with dynamic and personalized support and a cushioned. bouncy ride. The major changes lie in the upper. where Nike tweaks its Flyknit arrangement to better support the foot while also relieving pressure and tightness in certain areas to give your foot the supportive hug you’ve been missing from your life. Finally. a detached tongue helps increase the entry point into the shoe and allowing for better lockdown. If you’re on the fence. make sure you get your pair before they’re gone in a blink of an eye!
