FAQs
Are these trainers suitable for wide feet?
The UltraBoost series generally offers a comfortable fit, but the leather upper may be less forgiving than mesh. We recommend checking specific sizing guides and considering the 'Continental™ Stretchweb outsole' for its adaptive fit.
How do I break in the leather upper?
Wear the trainers around the house for short periods with comfortable socks. The leather will naturally mold to your foot over time, providing a personalized fit.
Can I machine wash these trainers?
No, machine washing is not recommended as it can damage the leather upper, the Boost midsole, and the adhesives, compromising the shoe's integrity and performance.
What is the main difference between this leather version and standard UltraBoosts?
The primary difference is the material of the upper. The leather version offers a more premium and durable aesthetic, while standard UltraBoosts typically feature a Primeknit or mesh upper for enhanced breathability and flexibility.
How long does the Boost technology typically last?
Boost technology is engineered for high durability and sustained cushioning. While it may gradually lose some of its responsiveness with very heavy, long-term use, many users report consistent comfort for hundreds of miles or years of regular wear.
Is the 'Core Black' colorway true to the image?
Yes, the 'Core Black' colorway refers to a deep, solid black throughout the shoe's primary components, providing a classic and versatile look.
Troubleshooting
Tightness in the leather upper
Wear the shoes with thick socks for a short period to gently stretch the leather. Alternatively, use a shoe stretcher if the tightness is significant.
Squeaking noise from the sole
Ensure the outsole is clean and dry. Sometimes, moisture trapped between the sole and the ground can cause squeaking. If the noise persists, a small amount of talcum powder under the insole might help.
Reduced cushioning or energy return over time
While Boost technology is durable, its optimal performance may slightly decrease with extensive use. Ensure the shoes are clean and properly dried after getting wet. Consider replacing the insoles if they are worn out.
Discoloration on the leather
Use a dedicated leather conditioner and cleaner specifically designed for black leather. Avoid abrasive materials when cleaning.
