NUCLEUS AIR - Black Grey - Low Shoes - 9.5

While comfortable for commuting and urban riding, their low-top design and emphasis on ventilation make them best suited for shorter to medium-distance rides or warmer weather. For long-distance or varied conditions, consider Sidi boots.

D3O® inserts are designed to absorb impact energy. They remain flexible for comfort during normal wear but stiffen instantly upon impact to provide a protective barrier for the ankle.

These shoes are highly ventilated with a mesh construction, meaning they are not waterproof. They are best suited for dry conditions. For wet weather riding, waterproof footwear is recommended.

Refer to the sizing chart and measure your foot length in UK sizing. The anatomical profile and ergonomic last aim for a comfortable fit, but it's essential to get the right initial size.

The D3O® inserts are maintenance-free. Their protective properties are inherent and do not degrade with normal use or cleaning of the shoe.

The Materiis sole offers good grip and comfort for walkability. While durable, frequent and extensive walking on abrasive surfaces may lead to faster wear compared to dedicated walking shoes.

Yes, the laces can be replaced. Sidi offers spare parts for many of their products, or standard shoe laces of a similar length and type can be used.

Ensure the laces are properly threaded through all eyelets and tied securely. Consider double-knotting if the laces tend to loosen during activity.

The Fortex® system and anatomical last may require a short break-in period. If discomfort persists, check lacing for over-tightening.

Ensure the mesh ventilation panels are clear of dirt and debris. Gently clean with a soft brush or damp cloth.

The Materiis compound is designed for optimal grip on typical riding surfaces. For extremely slick or polished surfaces, exercise caution as with any footwear.
