FAQs
Are the adidas Ultra Boost 20 good for wide feet?
The Primeknit upper offers a degree of adaptability, but individuals with very wide feet might find them snug. It's recommended to try them on if possible or consider sizing up if you typically require wider shoe options.
How much more Boost is in the Ultra Boost 20 compared to previous versions?
The Ultra Boost 20 features 20% more Boost material in the midsole, providing enhanced cushioning and energy return.
Can I wear these for casual everyday use?
Yes, the Ultra Boost 20 is highly regarded for its comfort and stylish 'Triple Black' design, making it an excellent choice for casual everyday wear.
What is the Continental outsole made of?
The outsole is made from Continental rubber, a compound known for its high durability and excellent grip, similar to what is used in high-performance tires.
How do I determine my UK shoe size?
Refer to adidas' official size chart or measure your foot length and compare it to the provided sizing guide. Generally, a UK size 4 is suitable for a foot length of approximately 23.5 cm.
What is the warranty period for these trainers?
Adidas typically offers a standard warranty against manufacturing defects. Please refer to the specific warranty information provided at the time of purchase or on the official adidas website for exact terms and duration.
Is the 'Triple Black' colorway breathable?
Yes, the Primeknit upper construction promotes breathability, allowing air to circulate and keep your feet cool, even in the all-black design.
Troubleshooting
Shoes feel too tight
Ensure laces are loosened before putting them on. The Primeknit upper will stretch slightly with wear, but if the fit is still too restrictive, consider trying a half-size up or checking alternative models.
Squeaking sound during movement
This can sometimes occur due to friction between the midsole and outsole, or trapped moisture. Ensure the shoes are dry. If the issue persists, try applying a small amount of talcum powder under the insole.
Reduced cushioning effect over time
While Boost foam is durable, its responsiveness can decrease with extensive wear and tear. Ensure proper cleaning and avoid extreme temperatures. If the cushioning significantly degrades, it may be time to consider replacement.
Traction is poor on wet surfaces
While the Continental outsole offers good grip, extremely slick surfaces can still be challenging. Ensure the outsole is clean from debris. For significantly wet conditions, exercise caution and consider shoes with more aggressive tread patterns if needed.

Care Instructions:
