FAQs

How do I find my correct shoe size?

Measure the length of your foot from the heel to the tip of your longest toe. Compare this measurement to the size chart provided in the product description. If your foot length falls between two sizes, choose the larger size for a more comfortable fit.

Are these shoes suitable for all types of running?

Yes, the Ultra Boost 21 is designed for versatile running, offering excellent cushioning and responsiveness suitable for daily training, long runs, and even marathons. They also perform well for walking and casual wear.

How should I clean my Ultra Boost 21 trainers?

Gently clean with a soft brush or cloth and a mild detergent solution with cool water. Avoid machine washing or using harsh chemicals. Allow them to air dry naturally.

What is the main benefit of the Boost technology?

Boost technology provides superior energy return, absorbing impact and converting it into responsive cushioning, which helps reduce fatigue and enhance performance during runs.

Can I wear these shoes in the rain?

The Continental™ Rubber outsole offers good traction, but extreme caution is advised on very wet or slippery surfaces. They are not waterproof but can handle light rain.

What materials are the shoes made of?

The shoes feature a Primeknit upper for a sock-like fit and breathability, and the midsole utilizes Boost cushioning technology. The outsole is made with Continental™ Rubber for durability and grip. Some versions may contain recycled materials.

What does 'Core Black/Cloud White/Pulse Aqua' refer to?

This refers to the colorway of the trainers. 'Core Black' is the primary color, 'Cloud White' and 'Pulse Aqua' are accent colors used in the design.

Troubleshooting

Shoes feel too tight

Ensure you have selected the correct size using the foot measurement guide. If still too tight, try loosening the laces and re-tying them more loosely. The Primeknit upper will stretch slightly with wear.

Reduced cushioning effect over time

The Boost midsole is designed for long-lasting cushioning, but wear and tear can occur. Ensure the shoes are clean and free from debris that might affect performance. For significantly degraded cushioning, it may be time to consider replacement.

Traction issues on wet surfaces

While the Continental™ Rubber outsole provides good grip, all shoes have limitations on extremely wet or slippery surfaces. Ensure the outsole is clean. For added confidence in wet conditions, consider alternative footwear specifically designed for such environments.

Setup, Compatibility & Care Instructions

Getting Started:

These trainers require no specific setup; they are ready to wear out of the box. Ensure you have selected the correct size before your first use.

Sizing:

Refer to the provided size chart to measure your foot length accurately. It is recommended to measure your foot at the end of the day when feet are typically larger. If your foot length falls between two sizes, it is generally advised to choose the next larger size for a more comfortable fit, allowing for potential swelling or the natural adaptation of the shoe.

Care Instructions:

Cleaning: Use a soft brush or cloth to remove loose dirt. For stains, use a mild detergent mixed with cool water and a soft cloth or brush. Avoid harsh chemicals or abrasive cleaners.
Drying: Allow the shoes to air dry naturally at room temperature. Do not place them near direct heat sources like radiators or in a tumble dryer, as this can damage the materials.
Storage: Store in a cool, dry place, away from direct sunlight, to maintain the integrity of the materials.

Compatibility:

These trainers are designed for running and general athletic activities. They are compatible with most standard athletic socks. For specific running techniques or conditions, consult with a running specialist.
