The Nike InfinityRN 4 represents an overhaul to the Nike Infinity React 3.
The new version comes with both a wider base for stability and a wider fit to accommodate runners with wider feet, and also packs in Nike’s new responsive React X foam for a smooth ride that will take you through however many miles you can throw at it. If you’re looking for a well cushioned shoe to keep you feeling good on easy runs, the Nike InfinityRN 4 is a worthy option.
WHY PACERS CARRIES THESE SHOES:
The Nike InfinityRN 4 is a running shoe built to keep your legs fresh so you can chase your goals day after day. This daily trainer comes with a stable ride and supportive cushioning, to give your foot the structure it needs. This highly cushioned and durable running shoe is perfect for beginner runners or anyone looking for a workhorse shoe for runs at easy paces.
WHAT’S NEW:
The first overhaul of Nike’s Infinity React line, the InfinityRN 4 takes what most runners liked about previous version of the shoe and turns them up a notch.
The new ReactX foam gives 13% more energy return with a 43% smaller carbon footprint than React foam. The Flyknit upper is even more structured and supportive than previous versions, and the InfinityRN 4’s new internal Flyknit fit band provides a secure fit around the midfoot. A wider toe box should fit many more feet than previous iterations as well.

HOW THEY COMPARE TO OTHER SHOES:
- CUSHION: The Nike InfinityRN 4 has a high level of soft cushion. For even more cushion, we recommend the Nike Invincible Run 3. For a lighter and more responsive ride, we recommend the Nike Pegasus 40.
- PRONATION: The Nike InfinityRN 4 is a neutral shoe with some stability features like a wider base and foam side walls. For a more neutral Nike shoe, we recommend the Nike Invincible Run 3.
- SPEED: The Nike InfinityRN 4 is too soft and heavy to really go fast. For workouts and races we recommend the Nike Zoom Fly 5 or the Nike ZoomX Vaporfly 3.
- OTHER BRANDS: Shoes from other brands similar to the Nike InfinityRN 4 include Saucony Endorphin Shift 3, Hoka Arahi 6, and Altra Paradigm 7.
