FAQs
What makes the Ultraboost 21 'Tokyo' different from previous models?
The Ultraboost 21 'Tokyo' features 6% more Boost capsules in the midsole for enhanced energy return and incorporates a Primeknit upper made from recycled ocean plastic.
Is the Primeknit upper waterproof?
No, the Primeknit upper is designed for breathability and is not waterproof. It is water-resistant to a degree but will soak through in heavy rain.
Can I wear these shoes for walking or casual use?
Yes, while designed for running, the comfort and cushioning of the Ultraboost 21 'Tokyo' make them suitable for walking and casual wear.
What is the primary benefit of the Boost midsole?
The Boost midsole provides exceptional energy return, cushioning, and responsiveness, helping to reduce fatigue during runs.
How should I clean my Adidas Ultraboost 21 'Tokyo' shoes?
Clean using a soft brush to remove loose dirt, and use a mild detergent with cold water and a soft cloth for deeper cleaning. Avoid machine washing.
Are these shoes suitable for wide feet?
The Primeknit upper offers some flexibility, but the shoe is designed for a standard or snug fit. Runners with very wide feet may find them too constrictive.
What does the 'Tokyo' designation signify?
The 'Tokyo' designation typically indicates a special edition colorway or design inspired by the city of Tokyo, often featuring unique aesthetic elements.
Troubleshooting
Shoes feel too tight or restrictive
Ensure you have selected the correct size. The Primeknit upper is designed to be snug; consider wearing thinner socks or allowing a break-in period of a few runs.
Reduced cushioning or responsiveness over time
While Boost cushioning is durable, performance can be affected by heavy wear and tear. Ensure the shoes are clean and free of debris that might impede the midsole's function. If the issue persists after significant mileage, consider replacement.
Slipping during runs
Check the outsole for excessive wear or debris. Ensure laces are tied securely. If the issue persists on wet surfaces, be aware of the limitations of any shoe's grip in such conditions.
