DescriptionThe whole story▼
Built to the exacting safety standards demanded by a multiple World Superbike Champion, the Sidi MAG 2 Air Álvaro Bautista Replica 2025 – 319 represents the most advanced fusion of certified rider protection, aerodynamic engineering and ventilation technology Sidi has ever produced. Every structural decision in this boot begins with safety, so you can push harder knowing your feet and ankles are as well defended as the rider who inspired the design.
Key Features
- Fiberglass and TPU reinforcements at every critical impact zone deliver race-proven structural protection against impacts and abrasion
- Integrated impact shields and tumble-reduction protection systems designed to minimise injury risk in the most violent crash scenarios
- NUUN 002M 3-Stage Holding System replaces traditional zippers with a three-level retention mechanism that locks the boot securely to the foot without pressure points — and releases quickly when you need it to
- Aerodynamic MotoGP-derived profile engineered for reduced drag, maximum stability and direct machine feedback at high speed
- Perforated ventilation zones, internal airflow channels and breathable high-tech materials keep temperatures controlled on track days and summer road rides alike
- Produced under Sidi's SBTi emissions-reduction programme, in alignment with the UN Sustainable Development Goals
Protection Without Compromise
The MAG 2 Air deploys Sidi's latest generation of armour across the entire boot structure. Impact shields guard against direct blows and abrasion, while the surrounding construction incorporates purpose-built tumble-reduction geometry — protection systems that absorb and redirect crash energy rather than transferring it to the rider. Critically, the movement zones are engineered around natural rider mobility, so protection never becomes a cage. Fiberglass and TPU reinforcements are positioned at every anatomically vulnerable point: ankle, shin, heel and toe.
NUUN 002M 3-Stage Holding System
The retention system fitted to the MAG 2 Air is a genuine step forward from the conventional zip closure. The NUUN 002M operates across three staged levels of stabilisation, wrapping the foot and lower leg progressively and evenly. The result is a more secure, more comfortable fit with no localised pressure and no movement inside the boot under braking or cornering load. In the event of a crash, the system is engineered to maintain structural integrity around the ankle far more effectively than a standard zip. Day-to-day, it opens and closes faster and with less friction than any traditional fastening.
Airflow Engineering
The Air designation is earned. Strategically placed perforated zones feed cooled air directly into the boot, internal ducting channels it across the foot, and the breathable high-tech upper material allows continuous moisture transfer. Whether you are completing back-to-back sessions on track, covering long summer sport-touring miles, or riding the Álvaro Bautista Replica livery for authenticity as much as performance, thermal comfort is maintained throughout.
Aerodynamic MotoGP Profile
The entire outer geometry of the MAG 2 Air is shaped around speed. The low-drag profile, sculpted forms and friction-minimising closures all serve the same objective: to keep the boot — and therefore the rider's leg — as aerodynamically neutral as possible at racing speeds. The direct result is improved stability, more precise feedback from the footpegs and a closer mechanical connection to the motorcycle. This is a boot built to accelerate you, not hold you back. Suited to circuit racing, aggressive road riding and ambitious track day riders who take their equipment as seriously as their lap times.
