Product Information

Full details

The Nike ReactX Infinity Run 4 is designed for adult male runners and fitness enthusiasts seeking a blend of high-level responsiveness and daily comfort. Its standout feature is the proprietary ReactX cushioning technology, which provides significant energy return, making it an excellent choice for long-distance training or everyday wear. While the trainer excels in comfort, prospective users should note that the specialized foam construction is optimized for road surfaces rather than technical off-road trails.

FAQs

Is the ReactX foam durable?

Yes, ReactX foam is engineered for high energy return and long-term durability, making it ideal for consistent daily use.

Can I use these for marathon training?

Absolutely, the cushioning system is designed specifically for long-distance training and providing support over extended periods.

How should I determine my size?

These trainers fit true to size for most users; ensure there is about a thumb-width of space between your longest toe and the front of the shoe.

Are these shoes suitable for flat feet?

The Infinity Run series includes stability elements that accommodate various foot shapes, though individual arch support needs may vary.

Can I wear these for gym workouts?

While primarily a running shoe, the stable platform makes them versatile enough for general gym activities like cardio or light weightlifting.

Troubleshooting

Feeling tightness in the midfoot area

Adjust the lacing pattern to be slightly looser across the bridge of the foot to allow for natural foot swelling during runs.

Visible dirt on the upper fabric

Use a soft brush to gently remove dry debris, followed by a light wipe with a damp cloth; avoid soaking the shoe.

Care Instructions:

  1. Cleaning: Wipe away surface dirt with a soft, damp cloth. Do not machine wash or use harsh detergents that can degrade the foam.
