FAQs
How do I clean the Primeknit upper?
Gently clean the Primeknit upper with a soft brush or cloth and a mild soap solution. Avoid machine washing and harsh detergents to preserve the material's integrity.
What is the main benefit of the Boost midsole?
The Boost midsole provides exceptional energy return, returning energy with every step to reduce fatigue and enhance running performance.
Are these shoes good for wide feet?
The Primeknit upper is adaptive and can accommodate various foot shapes, but individuals with significantly wide feet might find them snug. Consider trying them on if possible.
What is the 'Tokyo' edition?
The 'Tokyo' edition refers to a specific colorway and design theme inspired by the city of Tokyo, offering a unique aesthetic to the standard Ultra Boost 21 model.
How durable is the outsole?
The outsole is made with durable materials, including Continental Rubber in some versions, designed to provide excellent traction and withstand significant mileage.
Can I use these for trail running?
These shoes are primarily designed for road running. The outsole provides good grip on pavement and light gravel, but is not optimized for technical trail conditions.
Troubleshooting
Shoes feel too tight
Loosen the laces and re-tie them, ensuring a snug but not constricting fit. The Primeknit upper may need a few wears to fully adapt to your foot.
Slipping heel
Ensure the laces are pulled through all eyelets, including any secondary ones if available. Try a 'heel lock' lacing technique. Confirm you have the correct size.
Reduced cushioning feel
Boost foam is designed for long-term durability. While it maintains its properties for many miles, the initial responsiveness may feel less pronounced over extensive use. Ensure no debris is trapped in the outsole grooves.
Upper feels less supportive
Check that the laces are tied correctly and providing adequate lockdown. Ensure the shoe size is correct; an oversized shoe can make the upper feel less supportive.
