FAQs
Are these shoes suitable for long-distance running?
Yes, the UltraBoost 21 is engineered with high-rebound cushioning specifically to provide comfort and energy return during long-distance training.
Can I put my UltraBoost trainers in the washing machine?
It is not recommended to machine wash your trainers, as it can damage the structural integrity and the responsive properties of the Boost foam. Hand cleaning is preferred.
What is Primeblue material?
Primeblue is a high-performance recycled material made in part with Parley Ocean Plastic, reflecting adidas' commitment to sustainability.
Do these trainers provide arch support?
The shoe features a neutral support profile designed to accommodate most foot shapes with a balanced feel and adaptive fit.
Are these true to size?
The UltraBoost 21 generally fits true to size, but the knit upper offers a more snug, sock-like feel compared to traditional mesh trainers.
Troubleshooting
Knit upper feels too tight or constricting
Adjust the laces to a looser tension or try thinner performance socks to allow more volume.
Midsole foam feels dirty or discolored
Use a specialized sneaker cleaning solution or a mixture of baking soda and water with a soft toothbrush to gently scrub the foam areas.

Setup, Compatibility & Care
To ensure the longevity of your adidas UltraBoost 21 trainers, follow these care guidelines:
- Cleaning: Wipe away loose dirt with a soft brush after every run. For deeper stains, use a mild soap and a damp cloth; avoid submerging in water or using harsh detergents.
- Drying: Air dry only. Do not place them in the dryer or directly next to a heat source, as extreme heat can degrade the cushioning foam.
- Fit: Ensure you are wearing appropriate athletic socks. The knit material provides a flexible fit, but it is recommended to ensure your size (such as 7.5 UK) allows for a thumb's width of space at the toes.
- Storage: Store in a cool, dry place away from direct sunlight to prevent discoloration of the white fabric.
