DescriptionThe whole story▼
When visibility and certified race-level protection matter as much as lap times, the Sidi MAG 2 Air in Fluo Yellow / Coral Red – model 390 – answers the call. This is a boot built to MotoGP® standards, engineered with perforated airflow construction and high-impact TPU armour, then finished in a high-visibility colour combination that keeps you seen on road or track without sacrificing a single degree of performance.
Key Features
- Extreme airflow construction with perforated surfaces and strategically placed ventilation zones that keep your foot cool and dry during intense sessions
- Aerodynamic MotoGP®-inspired silhouette with integrated protection modules and optimised contours for stability at high speed
- TPU impact protectors and reinforced abrasion-resistant panels deliver race-grade shielding without restricting natural movement
- Flexible zones throughout the boot allow a full range of rider inputs while systems to reduce rotation and crash risk remain in place
- NUUN 002M 3-Stage Holding System — a three-point retention design that distributes pressure evenly, operates quickly and eliminates pinching, jamming or tearing
- High-visibility Fluo Yellow and Coral Red finish (model 390) actively improves rider conspicuity in traffic, combining safety signalling with an unmistakable race aesthetic
Certified Protection Meets Breathing Performance
The MAG 2 Air is the product of Sidi's long-standing Impact Science philosophy — a commitment to developing protective technologies that evolve alongside MotoGP® regulations and real-world crash data. The 390 colourway is no cosmetic afterthought: fluorescent yellow and coral red are proven high-conspicuity tones that give other road users a measurable extra fraction of a second to react. In a racing context, those same colours allow corner marshals and medical crews to locate a fallen rider quickly.
Protection is layered rather than monolithic. TPU impact protectors at critical strike zones handle concentrated impacts, while the reinforced abrasion panels spread load across a wider surface during a slide. Crucially, Sidi has retained flexible articulation zones at the ankle and instep, so the boot moves with your foot through the full repertoire of throttle, brake and gear-change inputs.
Airflow Engineering for Warm-Weather and High-Intensity Riding
The Air designation is a genuine performance specification. Perforated outer surfaces allow warm air to escape from the foot and calf, while directed ventilation channels draw cooler ambient air inward during forward motion. The breathable inner structure wicks moisture away from the foot, maintaining a stable microclimate even during back-to-back track sessions or long summer road rides. The result is a foot that stays controlled, comfortable and alert, not fatigued by heat build-up.
Aerodynamic Form Shaped by MotoGP®
Every external surface of the MAG 2 Air has been profiled to minimise turbulence and drag at the foot and lower leg. The smooth, streamlined silhouette reduces the aerodynamic footprint compared to traditional race boots, while the integrated protective modules sit flush rather than protruding into the airstream. At high speeds this matters for feel and stability; at any speed it means the boot presents a clean, professional look that reads immediately as purpose-built hardware.
NUUN 002M 3-Stage Holding System
Sidi's NUUN 002M replaces the conventional zip-and-buckle approach with a three-stage retention architecture. Each stage of the system bears a portion of the closing load, spreading pressure across the boot's upper rather than concentrating it at a single point. The mechanism is faster to operate than a traditional zip, requires less force to close securely and eliminates the common failure modes — pinching, jamming and sudden release — that compromise both comfort and confidence during a ride.
Sidi Impact Science and Sustainability
Sidi maintains active CO₂-reduction targets across its manufacturing operations and supports the United Nations Sustainable Development Goals. The MAG 2 Air is designed to be a long-service boot: materials and construction methods are selected with durability and repairability in mind, reducing the environmental cost of early replacement.
Fitment & Compatibility
The Sidi MAG 2 Air model 390 is a universal motorcycle racing and performance road boot sized by standard European footwear sizing (available in EU 39–47). It is compatible with any sportsbike, supersport or track-oriented motorcycle where a high-performance, properly fastening boot is required. No vehicle-specific fitment applies — size selection follows standard Sidi sizing guidelines.
