FAQs
Are the adidas UltraBoost 21 suitable for wide feet?
The Primeknit upper offers some flexibility, but the shoe is generally designed for a standard width foot. If you have particularly wide feet, it's advisable to try them on or consult sizing guides for potential wider options if available.
How do I clean the white Primeknit upper?
Use a soft brush with a mixture of cold water and mild soap to gently scrub the upper. Wipe away any residue with a damp cloth and allow to air dry.
What is the main benefit of the Boost midsole?
The Boost midsole is engineered to provide exceptional energy return and cushioning, absorbing impact and returning energy with each step for a more comfortable and responsive run.
Can these trainers be used for all types of running?
They are best suited for neutral runners and are excellent for road running, treadmill use, and daily training. They may not offer sufficient stability for runners who severely overpronate.
How durable is the outsole?
The outsole features Continental™ Rubber, which is known for its durability and excellent grip in both wet and dry conditions, providing long-lasting traction.
What does 'Oreo' colorway refer to?
The 'Oreo' colorway typically refers to a black and white combination, mimicking the colors of the popular cookie, giving the trainers a distinct and stylish appearance.
What is the warranty period for these trainers?
Warranty information is typically provided by the retailer. Please check the product packaging or the retailer's website for specific warranty details.
Troubleshooting
Shoes feel too tight
Loosen the laces and re-tie them, ensuring they are not overtightened. If the issue persists, consider if a different size or width might be more appropriate.
Slight squeaking sound
This can sometimes occur due to moisture between the insole and midsole. Try removing the insole and drying both thoroughly. Ensure the laces are not too tight, which can sometimes cause friction.
Reduced cushioning effect over time
While Boost technology is durable, extreme conditions or heavy use can eventually impact cushioning. Ensure the shoes are not exposed to excessive heat. Regular cleaning can also help maintain material integrity.
