FAQs
Are these shoes true to size?
Yes, the Ultraboost 20 fits true to standard UK adult sizing for most wearers.
Can I use these for long-distance marathons?
Many runners find the cushioning comfortable for long-distance training; however, shoe preference depends on personal gait and weight requirements.
Is the upper waterproof?
No, the Primeknit upper is designed for breathability and is not water-resistant or waterproof.
How do I clean the white Boost midsole if it discolours?
Use a mild soap solution and a soft brush to scrub the midsole, then wipe clean with a damp cloth.
Are these suitable for wide feet?
The Primeknit material is stretchy, which accommodates many foot shapes, though those with very wide feet may prefer to try them on for fit.
Troubleshooting
Knit upper feeling loose over time
Re-tie the laces using the 'runner's loop' method to improve heel lockdown and midfoot security.
Midsole foam showing surface creases
This is a normal characteristic of the expanded TPU material in Boost technology and does not affect the performance or longevity of the shoe.
Outsole collecting debris
Use a soft-bristled brush to gently remove rocks or grit trapped in the Continental rubber tread pattern.

Setup, Compatibility & Care
To ensure the longevity of your adidas Ultraboost 20 trainers, it is recommended to keep them clean by wiping down the midsole with a damp cloth after muddy runs. Avoid using a washing machine, as the heat and agitation can degrade the adhesive bonds and the structural integrity of the knit upper. For the best performance, allow the shoes to air dry naturally away from direct heat sources. Ensure you check the sizing guide, as these trainers typically follow standard UK adult sizing conventions.
