Full details
The adidas UltraBoost 21 'Tokyo' is designed for adult male runners seeking enhanced performance and a comfortable, stable ride. Its key benefit is the responsive Boost midsole and Primeknit upper made from recycled ocean plastic. A potential caveat is its specialized design, which may not suit all running styles or foot types. This innovative running shoe offers a snug fit, superior stability, and a more responsive feel due to an increased number of Boost capsules.

FAQs
What makes the 'Tokyo' edition special?
The 'Tokyo' edition is a special release that often includes unique colorways or design accents inspired by the city of Tokyo, building upon the core performance features of the UltraBoost 21.
Are these shoes suitable for trail running?
The UltraBoost 21 'Tokyo' is primarily designed for road running. While they may offer some grip on light trails, they are not optimized for the terrain, stability, or protection required for serious trail running.
How much more Boost is in this model compared to older versions?
The UltraBoost 21 features 6% more Boost capsules in its full-length Boost midsole compared to previous models, leading to an even more responsive and cushioned ride.
Can I wear these shoes for walking or everyday use?
Yes, the superior cushioning and comfort make them suitable for walking and casual wear, though their primary design and optimal performance are for running.
How do I know if I have the right size?
The shoe should feel snug but not constricting, with enough room in the toe box to wiggle your toes. Ensure there's no excessive pressure points, especially around the heel and midfoot.
What is the warranty period for these shoes?
Warranty information typically varies by retailer and region. Please check the original purchase documentation or the adidas website for specific warranty details.
Does the Primeknit upper offer good ventilation?
Yes, the Primeknit upper is engineered to be breathable, allowing air to circulate and help keep your feet cool during runs.
Troubleshooting
Shoes feel too tight or restrictive.
Ensure laces are loosened before putting on the shoes. The Primeknit upper will stretch slightly with wear, but if discomfort persists, consider if this is the correct size or model for your foot shape.
Reduced energy return or cushioning feels flat.
The Boost midsole is designed for long-term responsiveness. If performance seems diminished, ensure the shoes are not excessively worn. For a new pair, ensure you've broken them in sufficiently.
Dirt or stains on the Primeknit upper.
Use a soft brush or damp cloth with a small amount of mild soap to gently clean the affected area. Rinse with a clean damp cloth and allow to air dry.
