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, a redesigned upper for a more adaptive fit, and an improved Torsion System for better stability. The 'Tokyo' edition also includes specific design elements inspired by the city.
Are these shoes suitable for marathon running?
Yes, the significant Boost cushioning and responsive nature of the UltraBoost 21 make it an excellent choice for marathon training and racing, providing comfort and energy return over long distances.
Can I machine wash my UltraBoost 21 'Tokyo' shoes?
It is not recommended to machine wash these shoes, as it can damage the materials, adhesives, and overall structure. Hand cleaning with mild soap and water is the preferred method.
What is the Primeknit upper made from?
The Primeknit upper is made from recycled ocean plastic, contributing to a more sustainable manufacturing process.
How is the grip on wet surfaces?
The outsole is made with Continental Rubber, which provides excellent grip and traction in both wet and dry conditions, offering reliable performance.
Will the fit loosen over time?
The Primeknit upper is designed to adapt to your foot and may offer a slightly more relaxed feel after an initial break-in period. However, it is designed to maintain a snug and supportive fit.
What type of running are these shoes best for?
These shoes are best suited for road running, daily training, long-distance runs, and tempo workouts. They offer a blend of cushioning, responsiveness, and stability.
Troubleshooting
Shoes feel too tight or uncomfortable.
Ensure you have the correct size. The Primeknit upper will stretch slightly with wear, but if the fit is fundamentally too small, consider exchanging for a larger size. Wear with thinner socks if needed.
Reduced cushioning or energy return over time.
The Boost midsole is designed for long-lasting performance, but cushioning can feel less pronounced after extensive use. Ensure the shoes are clean and that there are no debris lodged in the outsole that might affect flexibility.
Slipping in wet conditions.
While the Continental rubber provides excellent grip, extremely slick surfaces can still pose a risk. Ensure your stride is balanced and cautious on very wet or icy surfaces.
Primeknit upper snagged or torn.
Carefully try to smooth out the snag. Minor snags may not affect performance, but significant tears may require professional repair or replacement of the shoes.
