FAQs
Are these trainers suitable for wide feet?
The Primeknit upper offers a flexible, adaptive fit that can accommodate various foot shapes. However, individuals with very wide feet might find them snug initially. They tend to offer more give than traditional rigid materials.
How do I clean the white parts of the 'Oreo' colorway?
For the white sections, use a soft brush and a mild soap solution with cold water. Gently scrub the area and wipe clean with a damp cloth. It's best to address stains as soon as possible.
What is the main difference between Ultraboost 21 and previous models?
The Ultraboost 21 features an updated Boost midsole for even greater energy return and a redesigned heel counter for enhanced support. It also incorporates a Linear Energy Push (LEP) system for a more responsive feel.
Can I wear these for marathon running?
Yes, the Ultraboost 21 is highly regarded for its cushioning and energy return, making it a popular choice for marathon runners. However, personal preference for shoe feel and support is crucial for marathon distances.
What does 'Oreo' refer to in the colorway name?
'Oreo' is a common nickname for colorways that feature a distinct black and white pattern, reminiscent of the popular cookie.
Are these shoes waterproof?
No, the Primeknit upper is designed for breathability and is not waterproof. They are suitable for dry conditions or light rain but will not keep your feet dry in heavy downpours.
Troubleshooting
Fit feels too tight
Ensure laces are loosened before putting on. The Primeknit upper will stretch slightly with wear. If still too tight, consider a half-size larger.
Reduced cushioning feel over time
The Boost midsole is designed for long-term energy return. If the cushioning feels diminished, ensure the shoes are not excessively worn. Clean the shoes to remove any dirt that might be affecting performance.
Traction is poor on wet surfaces
The outsole provides good traction under normal conditions. For very wet surfaces, exercise caution as with any footwear. Ensure the outsole is clean of debris.
