FAQs
What is the primary benefit of the Ultraboost 21?
The primary benefit is the unparalleled comfort and energy return provided by the Boost midsole, making them suitable for both intense training and daily wear.
Are these trainers suitable for all types of running?
They are excellent for road running and general training. For highly technical trails or specific sports requiring rigid support, other specialized footwear might be more appropriate.
How do I ensure the best fit?
Select your standard UK size. The Primeknit+ upper offers a flexible fit, but you can adjust the tightness by re-lacing the shoes.
What does 'Crew Navy' refer to?
'Crew Navy' refers to the primary color scheme of these specific trainers.
Can I wash these in a washing machine?
It is not recommended to machine wash the adidas Ultraboost 21. Hand washing with mild soap and air drying is the preferred method for cleaning.
Are these trainers good for wide feet?
The Primeknit+ upper offers a degree of adaptability, but individuals with significantly wide feet may find them snug. It's best to try them on if possible or consult size guides.
What is the Torsion System for?
The Torsion System provides midfoot stability and allows for a more natural transition between the heel and the forefoot during movement.
Troubleshooting
Reduced cushioning or energy return.
The Boost midsole can accumulate dirt. Clean the midsole thoroughly with a damp cloth and mild soap. Ensure the shoes are not excessively worn.
Uncomfortable or tight fit.
Ensure you have selected the correct size. The Primeknit+ upper is designed to be snug; try loosening the laces slightly and re-tying them to customize the fit.
Slipping during activity.
Check the Continental™ Rubber Outsole for excessive wear or debris. Clean the outsole. Ensure the footwear is appropriate for the surface being used.
