Product Information

Full details

The Nike React Infinity Run Flyknit 3 is engineered for adult runners seeking a perfect balance of plush cushioning and structural support for their daily mileage. Featuring responsive React foam and an adaptive Flyknit upper, this trainer is an excellent choice for athletes focused on comfort and injury prevention; however, its specialized design prioritizes stability over pure speed, which may not suit those looking for a lightweight racing flat.

Extended Product Information

FAQs

Are these shoes suitable for wide feet?

The Flyknit upper is flexible and adaptive, which generally accommodates various foot shapes, though runners with very wide feet may prefer to try them on for fit.

Can I use these for trail running?

These trainers are designed for paved surfaces and roads; the outsole does not have the deep lugs required for technical trail terrain.

How should I wash the Flyknit material?

We recommend hand washing with a soft brush and lukewarm water. Do not put these in a washing machine or dryer.

Is this a neutral or stability shoe?

The Infinity Run line is classified as a support shoe, designed to provide stability for those who need a bit of guidance through their stride.

How long should the foam last?

Typically, the cushioning remains effective for 300 to 500 miles, depending on your running style and surface conditions.

Troubleshooting

Knit upper feels too tight or constricting

Adjust the lacing pattern to be looser through the midfoot to allow the Flyknit material to expand naturally.

Accumulation of dirt on the white exterior

Use a specialized sneaker cleaner or a mild detergent cloth to spot clean the white areas immediately after use.

Foam feeling less responsive after many miles

Rotate your footwear to allow the foam cells time to decompress between sessions.

Setup, Compatibility & Care

To ensure the best experience, ensure you have selected your correct UK size for a snug, performance-oriented fit.

Care Instructions:

  1. Cleaning: Gently scrub the Flyknit upper with a soft brush and mild soapy water. Avoid submerging the shoes fully.
  2. Drying: Air dry naturally away from direct heat sources like radiators to prevent midsole degradation.
  3. Storage: Store in a cool, dry place out of direct sunlight to maintain the integrity of the foam and fabric color.
  4. Maintenance: Regularly remove pebbles or debris from the outsole tread to maintain traction.
