FAQs
Is the UltraBoost 4.0 suitable for flat feet?
The UltraBoost provides a neutral support profile. If you require significant arch support, you may wish to swap the factory insole for a specialized orthotic insert.
Can I put these shoes in the dryer?
No. Never put these shoes in a dryer, as high heat will damage the foam midsole and the adhesives used in construction.
Are these shoes water-resistant?
The upper is designed for breathability, meaning it is not waterproof. It is best used in dry or light rain conditions.
How often should I replace my running shoes?
Generally, running shoes should be replaced every 300 to 500 miles, depending on your running style and surface conditions.
Do these run true to size?
Most users find the UltraBoost 4.0 to fit true to size, but the knit upper offers a snug fit. If you prefer a roomier toe box, some users choose to size up by half a size.
Troubleshooting
Knit upper feels too loose after extended use
Re-tie the laces using the eyelets to customize the lockdown; consider using an 'extra hole' lacing technique to secure the heel.
Outsole collecting debris in the tread
Use a blunt tool or a stiff-bristled brush to gently dislodge gravel or debris caught in the rubber grooves after outdoor runs.
Midsole foam appears discolored or stained
Gently scrub the Boost midsole using a damp cloth with a small amount of dish soap, then rinse thoroughly and air dry.

Setup, Compatibility & Care
To ensure your UltraBoost shoes last, proper maintenance is essential.
- Break-in Period: Wear the shoes for short intervals initially to allow the knit upper to mold to your foot shape.
- Cleaning: Remove surface dirt with a soft brush. For deep cleaning, hand wash the upper with a mild detergent and cool water; avoid using a washing machine or tumble dryer, as heat can compromise the structural integrity of the foam and glue.
- Storage: Always store in a cool, dry area away from direct sunlight to prevent UV degradation of the rubber outsole and knit fabric.
- Compatibility: Best paired with performance-oriented running socks that wick moisture to optimize the benefits of the breathable upper.
