Sidi NUCLEUS AIR - Boots - UK 10

The Sidi NUCLEUS AIR Boots are designed for comfort and breathability, making them suitable for moderate-distance urban commuting and light touring. For very long-distance or extreme touring, consider boots with more robust construction and specialized features.

Refer to the Sidi sizing chart or measure your foot length and compare it with the provided size guide. Given the anatomical fit, ensuring the correct size from the start is important.

The D3O® inserts are integrated for protection and comfort and are not designed for user removal.

The Fortex® patented system provides enhanced internal stability to the boot structure without sacrificing flexibility, offering a balance of support and freedom of movement.

Clean your boots after rides where they have been exposed to significant dirt or moisture. For general use, a light wipe-down as needed will suffice to maintain their appearance and material integrity.

Please refer to the Sidi official warranty policy for details, as warranty periods can vary by region and retailer.

Ensure the lacing system is clean and free of debris. Try lacing in a criss-cross pattern, adjusting tension at each eyelet step-by-step.

Loosen the laces slightly, especially around the midfoot. The anatomical profile might require a break-in period; continuous minor adjustments can help find the perfect fit.

The Materiis compound sole offers good grip, but always exercise caution on very wet or slick surfaces. Ensure the sole is clean of mud or debris.

D3O® inserts are designed to be flexible during normal movement and stiffen on impact. Some initial stiffness is normal and will likely become less noticeable with use.
