FAQs

Are these shoes suitable for wide feet?

The Primeknit upper offers a degree of flexibility and adaptability. While not specifically designed for wide feet, many users find the material accommodates different foot shapes comfortably. Consider trying them on if possible or checking user reviews for feedback on fit.

How do the NASA and ISS US National Lab collaborations influence the shoe?

The collaboration signifies that the shoe's design and materials have undergone testing and received insights from environments and conditions similar to those experienced in space, focusing on durability, comfort, and performance under stress.

What is the primary difference between Ultraboost 20 and previous models?

The Ultraboost 20 features specific material enhancements and the NASA collaboration focus, aiming for improved performance and durability. The Boost midsole technology remains a core component, offering consistent energy return.

Can I wear these for everyday casual use?

Yes, the Ultraboost 20 provides exceptional comfort and cushioning, making them ideal for all-day wear and casual outings, in addition to athletic activities.

How durable is the Boost midsole?

The Boost midsole is known for its durability and long-lasting cushioning. It is designed to maintain its responsiveness over a significant number of miles or usage hours.

What is the recommended activity for these trainers?

These trainers are highly recommended for running, cross-training, gym workouts, and general athletic activities. They also offer superior comfort for extended periods of walking or standing.

How do I ensure I get the right size?

Refer to adidas's official sizing guide. These shoes generally fit true to size for most users. Consider your preferred fit (snug or roomier) and the type of socks you typically wear when making your selection.

Troubleshooting

Shoes feel too tight or constrictive.

Ensure you have selected the correct size. If the Primeknit upper feels snug, try wearing them for short periods to allow them to adapt to your foot shape. Loosen the laces to create more space.

Reduced cushioning or responsiveness.

The Boost midsole is designed for long-term performance. If you notice a significant decrease, ensure there are no debris or damage affecting the sole. The shoes have a very long lifespan, but performance may naturally decrease after extensive use.

Slipping during activity.

Check the rubber outsole for excessive wear or accumulated dirt. Clean the outsole with a damp cloth to restore grip. Ensure laces are tied securely for a stable fit.

Discoloration on the iridescent elements.

The iridescent finish may be sensitive to certain chemicals. Clean gently with mild soap and water. Avoid abrasive cleaners or prolonged exposure to harsh sunlight, which can affect the finish over time.

Setup, Compatibility & Care

Setup: These are ready-to-wear shoes. Ensure you select the correct size for optimal fit and comfort.

Compatibility: Suitable for a wide range of athletic activities including running, gym workouts, and daily wear. They are designed for adult use.

Care Instructions:

  1. Cleaning the Upper: For the Primeknit upper, use a soft brush or cloth with cool water and mild soap to gently scrub away dirt. Avoid harsh chemicals.
  2. Cleaning the Midsole and Outsole: Wipe the Boost midsole and rubber outsole with a damp cloth. For stubborn marks, a slightly stronger soap solution can be used, followed by a rinse with a clean, damp cloth.
  3. Drying: Allow the shoes to air dry naturally at room temperature. Do not place them near direct heat sources like radiators or in a tumble dryer, as this can damage the materials.
  4. Laces: Remove laces for separate cleaning if heavily soiled. Machine wash in a mesh bag or hand wash with soap and water.
  5. Storage: Store in a cool, dry place away from direct sunlight when not in use.
