Product Information

Full details

The adidas UltraBoost 4.0 DNA is designed for adult athletes and casual wearers seeking a blend of high-performance cushioning and everyday comfort. Its primary benefit is the signature responsive energy return provided by the full-length Boost midsole combined with a flexible, sock-like upper. While the shoe offers exceptional comfort, the Primeknit fabric may require extra care to avoid snagging on rough surfaces during outdoor activities.

FAQs

Are these shoes true to size?

Yes, they generally fit true to size. If you prefer a looser fit or have wider feet, you may consider a half-size up.

Can I use these for marathon running?

While the UltraBoost is comfortable, it is better suited for daily training, recovery runs, or walking rather than elite-level marathon racing.

Is the material waterproof?

No, the Primeknit material is breathable and will absorb water if exposed to heavy rain or puddles.

How long does the Boost midsole last?

Boost technology is highly durable; you can typically expect between 300-500 miles of performance before the foam begins to compress significantly.

Can I remove the insoles?

Yes, the insoles are removable, allowing you to insert your own custom orthotics if required.

Troubleshooting

Knit upper feels loose after extended wear

Re-tie the laces to ensure the midfoot cage is properly secured to your foot shape.

Outsole collecting small debris

Use a toothpick or soft brush to carefully remove gravel or twigs from the gaps in the Continental rubber grid.

Setup, Compatibility & Care

To ensure the longevity of your adidas UltraBoost 4.0, avoid putting them in the washing machine or tumble dryer, as heat can degrade the foam and glue.

  1. Cleaning: Use a soft-bristled brush and mild soap with cold water to spot-clean the knit upper.
  2. Drying: Air dry in a cool, shaded area away from direct sunlight.
  3. Compatibility: These shoes perform best with moisture-wicking synthetic or merino wool socks to prevent friction inside the knit fabric.
  4. Storage: Store in a dry, ventilated area to prevent odors and maintain the integrity of the Boost foam.
