FAQs
Are these shoes suitable for wide feet?
The Primeknit+ upper offers a flexible and adaptive fit, which generally accommodates a range of foot widths. However, for very wide feet, trying them on before purchase is recommended.
What is the main benefit of the Boost technology?
Boost technology provides exceptional energy return, cushioning your stride and giving you a responsive feel with every step.
How do I clean the Primeknit+ upper?
Use a soft brush to remove dirt and a damp cloth with mild soap and water for cleaning. Avoid harsh chemicals or machine washing.
What is the warranty period for these trainers?
Warranty information is typically provided by the retailer. Please refer to the purchase details or contact the seller for specific warranty terms.
Can I use these for trail running?
The Continental™ Rubber outsole offers good grip, but these trainers are primarily designed for road running and general athletic activities. They are not specifically designed for rugged trail terrain.
What does 'Crew Navy/Crew Navy/Core Black' refer to?
This refers to the official colorway of the trainers. 'Crew Navy' is the primary color, with 'Core Black' likely used for accents or the sole.
Troubleshooting
Shoes feel too tight
Loosen the laces and re-tie them, ensuring not to overtighten. The Primeknit+ upper will naturally adapt over time with wear.
Slight color difference from online image
Colors may vary slightly due to screen display settings. Refer to the product description for the official colorway (Crew Navy/Crew Navy/Core Black).
Reduced grip on wet surfaces
While the Continental™ Rubber outsole provides excellent grip, extreme wet conditions may still pose a slipping hazard. Exercise caution.
Discomfort during first wear
New shoes may require a short break-in period. Wear them for shorter durations initially and gradually increase wear time as they conform to your foot.
