FAQs
Are these shoes true to size?
Yes, they generally follow standard adult UK sizing; however, if you plan to wear thick performance socks, some users prefer a half-size up.
Can I use these for marathon running?
Absolutely, the cushioning system is designed specifically to offer support over long distances.
Is the Primeblue material durable?
Yes, Primeblue is a high-performance recycled textile engineered to withstand the rigors of athletic activity.
What should I do if the white upper gets stained?
Spot clean the area immediately using a soft-bristled brush and a mild cleaning solution to prevent deep penetration into the fabric.
Does the Torsion System interfere with natural movement?
No, it is designed to mimic the natural mechanics of the foot, providing support exactly where and when you need it during the gait cycle.
Troubleshooting
Feeling of slipping at the heel
Try using a runner's loop (lace lock) with the top eyelets to secure your ankle more firmly in the heel cup.
Midsole foam appears slightly compressed
This is a natural characteristic of responsive foam; rotate your shoes with another pair to allow the Boost material to decompress fully between runs.
Pros and Cons
Pros
- Exceptional cushioning for long-distance comfort
- Stable ride thanks to the integrated Torsion System
- Sustainable design using recycled materials
- Durable build quality suitable for daily training
Cons
- Boost midsole adds noticeable weight compared to racing shoes
- White colorway is prone to showing dirt
- May require a break-in period for optimal comfort
Setup, Compatibility & Care
To ensure the longevity of your UltraBoost 21s, follow these guidelines:
Setup: Upon receiving your shoes, lace them comfortably so that the tongue sits flush against your midfoot. Ensure the heel cup holds your ankle firmly without pinching.
Compatibility: These trainers are designed for neutral runners. If you have severe pronation issues, you may wish to use custom orthotic insoles inside the shoe to supplement the existing support.
Care: To clean, wipe down the upper with a soft cloth and mild soap. Avoid putting these shoes in the washing machine or dryer, as excessive heat can degrade the integrity of the Boost foam. Air dry them in a cool, shaded area away from direct sunlight.
