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 a more robust Torsion System for added stability. The upper is also made from Primeknit derived from recycled ocean plastic.
Are these shoes suitable for wide feet?
The Primeknit upper offers a flexible and adaptive fit, but the overall construction is designed for a standard fit. Users with particularly wide feet might find them snug. It's recommended to try them on if possible.
How do I clean the Primeknit upper?
Gently clean the Primeknit upper with a soft brush and a solution of mild detergent and cold water. Use a damp cloth or sponge. Avoid machine washing or harsh chemicals.
Can I use these for trail running?
These shoes are primarily designed for road running and offer excellent grip on asphalt and pavements. They are not recommended for technical trail running, as the outsole pattern and cushioning are optimized for smoother surfaces.
What is the warranty period for these shoes?
Warranty information typically varies by retailer and region. Please refer to the product packaging or the retailer's website for specific warranty details.
Is the Boost midsole durable?
Yes, the Boost midsole is engineered for long-term durability and consistent performance, even in varying temperatures. However, like all footwear, its cushioning properties may gradually reduce with extensive use over time.
Troubleshooting
Shoe feels too tight or snug
Ensure you are wearing appropriate athletic socks. The Primeknit upper will mold to your foot over time, but a short break-in period may be necessary. If discomfort persists, consider if this specific fit is suitable for your foot shape.
Reduced cushioning or responsiveness
The Boost midsole is designed for durability, but its performance can be affected by extreme temperatures. Ensure the shoes are clean and free from debris that might impede the sole's function. For very old shoes, cushioning may naturally decrease over time.
Slipping on wet surfaces
While the Continental rubber outsole offers excellent grip, extremely slick surfaces can still pose a challenge. Ensure the outsole is free of mud or debris. Run with caution on highly polished or wet surfaces.

Setup, Compatibility & Care
Setup: These are running shoes and require no setup. Simply wear them for your intended activity.
Compatibility: Designed for road running and general athletic activities. Compatible with most athletic socks. Not designed for technical trail running or rugged terrain.
Care:
- Cleaning: Remove excess dirt with a soft brush. Use a mild detergent and cold water with a damp cloth or sponge to clean the upper and midsole. Avoid harsh chemicals or abrasive cleaners.
- Drying: Allow shoes to air dry naturally at room temperature. Do not use direct heat sources like radiators or hairdryers, as this can damage the materials. Stuffing with newspaper can help absorb moisture and maintain shape.
