FAQs

Are these shoes suitable for running?

Yes, the UltraBoost 21 is engineered specifically for performance running and high-intensity training.

Do these trainers fit true to size?

They generally fit true to size, but the sock-like construction provides a snug feel that some users find tight; consider trying your standard size first.

Can I put these in the washing machine?

It is recommended to clean them by hand to prevent damage to the structural integrity of the knit and midsole.

What is the primary benefit of the Boost midsole?

The Boost midsole offers high energy return, meaning it absorbs energy from your foot strike and releases it to help propel you forward.

Are these shoes waterproof?

No, the knit upper is designed for breathability, not for water resistance.

Can I use these for heavy weightlifting?

While comfortable for cardio, the responsive, soft nature of the Boost foam may feel less stable for heavy squats or deadlifts compared to specialized lifting shoes.

Troubleshooting

Shoes feel too tight across the midfoot

Adjust the lacing system to be looser, or ensure you are wearing thin performance socks.

Visible dirt on the white exterior

Use a soft-bristled brush with a gentle detergent solution to spot clean the affected areas.

Setup, Compatibility & Care

To ensure your adidas UltraBoost 21 trainers maintain their performance, follow these guidelines:

Sizing: These shoes utilize a precision fit; verify your specific UK size, as the knit upper does not stretch like traditional leather.
Cleaning: Wipe down the Cloud White upper with a damp cloth and mild soap. Avoid submerging the shoes in water or using harsh chemicals that could damage the knit fibers.
Air Drying: Always let your trainers air dry at room temperature. Avoid direct sunlight or heat sources, which can warp the cushioning materials.
Storage: Store in a cool, dry place to maintain the integrity of the Boost foam.
