Sidi MAG 2 Air Motorcycle Boots White Black - 203

Constructed from materials and technologies refined in the MotoGP® paddock, the Sidi MAG 2 Air in White/Black – model 203 – represents the kind of uncompromising build quality that separates a proper racing boot from everything else on the shelf. Every component, from the TPU protection modules to the ventilated sole, has been selected and engineered to perform at the limit, whether that limit is a track day chicane or a demanding alpine pass.

Key Features

• Aerodynamic profile derived directly from MotoGP® race boot development, with streamlined forms and optimised contact surfaces for stability at high lean angles
• NUUN 002M 3-Stage Holding System – a tri-point retention mechanism that delivers a more precise, secure fit than conventional zip or buckle closures, adjustable even on the move
• TPU impact and abrasion protectors paired with rotation-force reduction modules, keeping protection comprehensive without sacrificing natural foot movement
• Dedicated airflow construction: ventilated sole, breathable material panels and ventilation channels positioned at critical heat zones for cool performance across long stints
• Flat inner surface for unfiltered feedback through the footpeg – sharper gear changes, more confident braking, direct power transfer
• Flexible zones engineered around the natural articulation of the foot, so protection never becomes a barrier to control

Build Quality and Materials

Sidi's approach to the MAG 2 Air prioritises longevity alongside performance. The chassis of the boot uses a rigid yet articulated structure capable of withstanding the demands of repeated high-intensity riding. TPU protectors are integrated rather than surface-mounted, meaning they stay precisely where they need to be under impact. The closure hardware is purpose-designed to resist the vibration and heat cycles of sustained track use, and every flexible zone is calibrated to flex predictably rather than collapse under load. The White/Black 203 colourway is executed with the same attention to finish that Sidi applies to the structural elements — clean, purposeful and built to remain presentable after hard use.

Airflow and Thermal Management

The 'Air' designation reflects a genuine engineering commitment rather than a marketing label. The ventilated sole draws heat away from the underside of the foot, breathable material zones promote airflow across the upper, and ventilation channels are routed through areas that generate the most heat during sustained riding. The result is a boot that remains comfortable through track days in warm conditions, summer sport touring and back-to-back sessions where a sealed boot would leave feet fatigued before the lap count does.

The NUUN 002M 3-Stage Holding System

Where a traditional zip simply closes a boot, the NUUN 002M works across three distinct retention points to lock the foot and lower leg in a consistent, repeatable position. Pressure is distributed evenly rather than concentrated at a single closure, eliminating the hot spots and slippage that compromise feel. Fine adjustment is accessible without removing gloves, so fit can be dialled in at the side of the track or adapted as the day's conditions change. The outcome is a boot that behaves like part of the rider rather than an item worn over the rider.

Fitment and Compatibility

The Sidi MAG 2 Air is a sport and racing motorcycle boot suitable for riders across all categories of performance motorcycle — supersports, superbikes, and track-dedicated machines. It is intended for riders who demand genuine racing-derived protection and feedback characteristics, whether competing on circuit or riding at a high level on public roads. Available in European sizes 39 through 47 in the White/Black 203 colourway.

Sustainability

Sidi continues to align its production practices with the UN Sustainable Development Goals, pursues CO₂ reduction targets in line with Science Based Targets initiative (SBTi) commitments, and maintains a philosophy of durable, responsible manufacturing — so the boot you buy is built to last rather than to be replaced.
