Keep your feet cooler through hot, humid rides
Daily rides in Malaysia's heat can quickly become uncomfortable when your footwear traps warm air around your feet. The Sidi Nucleus Air is built to maximise ventilation while still giving you the motorcycle-specific protection needed for urban riding and commuting.
Its high-tenacity mesh upper lets cooling air circulate around the foot, while reinforced zones add durability and protection where they are needed. Inside, Fortex provides supportive structure without taking away the natural flex required for walking, and D3O protects the ankles while remaining comfortable during normal movement.
The extended lacing system helps hold the foot securely, while the Materiis sole balances grip, comfort and walkability for days that continue after you park the bike.
Key benefits
- Highly ventilated mesh upper: Maximises airflow to reduce heat build-up in hot and humid conditions
- Fortex structure: Adds support while allowing the foot to flex naturally when walking
- D3O ankle protection: Stays flexible as you move and firms up on impact
- Extended lacing: Helps hold the foot securely and lets you fine-tune the fit
- Reinforced zones: Add durability and protection without blocking airflow
- Materiis sole: Balances grip, comfort and walkability for urban use
- CE Level 1: Certified to EN 13634:2017 with a 1-1-1-1 rating
The Nucleus Air offers the highest airflow in this Sidi range, making it the strongest choice for hot-weather commuting and urban riding. It is not designed for wet-weather protection, but it helps you finish warm rides with cooler, more comfortable feet.

What is D3O?
D3O is a flexible impact-protection material. It stays soft while you move, then firms up on impact to help absorb and disperse energy around the ankle.
What is Fortex?
Fortex is Sidi's internal support structure. Its segmented design helps the shoe resist forces in a motorcycle accident while still allowing the foot to flex naturally when walking.
Is the Nucleus Air waterproof?
No. Its mesh construction is designed to maximise airflow rather than keep water out.
How do I choose my size?
Measure from your heel to your longest toe and compare the measurement with the Sidi footwear size chart."
