FAQs

Are these shoes true to size?

Yes, they generally fit true to size, but the sock-like upper provides a snug fit that some users find tight.

Can I use these for long-distance running?

Absolutely, the Ultraboost 21 is specifically designed with extra cushioning to support the feet over long distances.

Are they machine washable?

No, machine washing can degrade the materials and foam technology. Stick to hand cleaning.

Do these provide arch support?

While not a medical orthotic, the construction offers a stable platform that provides good neutral arch support.

Is the white material hard to keep clean?

Like any white footwear, they will show dirt more easily than darker colors, so regular spot cleaning is advised.

Can I replace the insoles?

Yes, the insoles are removable if you prefer to use your own custom orthotics.

Troubleshooting

Feeling pressure on the top of the foot

Try adjusting the lacing pattern to be looser across the midfoot to reduce tension.

Difficulty putting the shoe on

Use a shoehorn to help slide your heel into the sock-like opening without damaging the heel counter.

Midsole foam getting dirty

Use a soft-bristled brush and warm water mixed with a drop of gentle detergent to scrub the foam.

Pros and Cons

Pros

  • High level of energy return
  • Excellent underfoot cushioning for long wear

  • Clean and versatile visual design

Cons

  • Snug fit may feel restrictive for wide feet
  • White fabric requires consistent maintenance to stay clean
  • Higher price point compared to basic trainers

Setup, Compatibility & Care

To ensure your Ultraboost 21s last, wear them for shorter durations initially to allow the upper to conform to your specific foot shape. Because these trainers feature a white exterior, it is recommended to treat the mesh with a water-repellent spray before first use to prevent staining. When cleaning becomes necessary, wipe down the midsole with a damp cloth and mild soap. Avoid putting these trainers in a washing machine or dryer, as high heat can damage the integrity of the foam cushioning and the fabric adhesive. Store them in a cool, dry place away from direct sunlight to prevent material yellowing.
