FAQs

Are the adidas UltraBoost 4.0 DNA true to size?

Sizing can vary slightly between individuals. Many users find them to fit true to size, but if you are between sizes, it's often recommended to go up half a size for a more comfortable fit, especially if you prefer more room in the toe box.

Can I wear these trainers for running?

Yes, the UltraBoost 4.0 DNA are suitable for casual running and shorter distances thanks to their excellent cushioning. For serious or high-mileage running, dedicated running shoes might offer more specialized support and features.

How do I clean the white Primeknit upper?

Use a soft brush or cloth with a mild soap solution. Gently scrub the stained areas. For tougher stains, a specialized shoe cleaner designed for knit materials can be used. Always rinse with a damp cloth and air dry.

Is the Torsion System important?

The Torsion System provides stability to the midfoot, allowing the shoe to move more naturally with your foot during movement and enhancing support.

What is the main difference between the 4.0 DNA and other UltraBoost models?

The 'DNA' designation often indicates a lifestyle-oriented interpretation of a performance shoe, focusing on comfort and style for everyday wear, sometimes using materials or designs inspired by earlier performance models.

How durable is the BOOST midsole?

The BOOST midsole is known for its durability and ability to maintain its cushioning properties over a long period, even in varying temperatures. However, like all foams, it will eventually degrade with extensive use.

Troubleshooting

Unusual squeaking sound

This can sometimes occur due to friction between the shoe components or moisture. Try inserting a talc-free powder inside the shoe or ensuring all parts are dry.

Stiff or uncomfortable fit

The Primeknit upper may need a short break-in period. Wear the shoes for short durations initially and gradually increase wear time. Ensure the laces are adjusted correctly, not too tight or too loose.

Slippery outsole on wet surfaces

While the outsole provides good traction, extreme wet conditions can reduce grip. Exercise caution on very slick surfaces. Ensure the outsole is clean of mud or debris.

BOOST foam appears discolored

BOOST foam can naturally yellow over time with exposure to UV light and wear. This is a cosmetic change and does not typically affect performance. Regular cleaning can help minimize this.

Setup, Compatibility & Care

Setup:

These trainers require no setup. They are ready to wear straight out of the box. Ensure you have selected the correct size for optimal comfort and performance.

Compatibility:

The UltraBoost 4.0 DNA is designed as a unisex trainer, compatible with a wide range of foot shapes due to its flexible Primeknit upper. They are suitable for various activities, from walking and casual wear to light athletic pursuits.

Care Instructions:

  • Cleaning: Gently clean the upper with a soft brush or cloth and mild soap. Avoid abrasive cleaners.
  • Midsole: Wipe the BOOST midsole with a damp cloth. Stubborn marks may require a specialized shoe cleaner.
  • Outsole: Clean the rubber outsole with water and a brush to remove dirt and debris.
  • Drying: Allow shoes to air dry naturally at room temperature. Avoid direct heat sources like radiators or dryers, as this can damage the materials.
  • Washing Machine: It is generally not recommended to machine wash these shoes, as it can degrade the adhesives and materials.
