DescriptionThe whole story▼
When every tenth of a second and every degree of lean angle matters, the Sidi MAG 2 Air in White/Black/Red – 391 delivers the safety architecture and aerodynamic precision that MotoGP®-inspired engineering demands. Built for riders who refuse to compromise between protection, control and ventilation, this boot brings genuine race-derived technology to the track day and the canyon road alike.
Key Features
- MotoGP®-inspired aerodynamic profile with integrated protection modules and reduced friction geometry for high-speed stability
- TPU impact protectors and high-impact shields guard critical zones without restricting natural foot movement
- Dedicated systems to reduce rotational forces during impact — protection that goes beyond simple abrasion resistance
- NUUN 002M 3-Stage Holding System replaces conventional zips with a three-point closure that can be fine-tuned in seconds, even while riding
- Ventilated sole, breathable materials and dedicated airflow channels keep feet cool throughout intensive sessions
- Flat inner contact surface engineered for optimal footpeg feel, precise gear changes and maximum bike connection
Protection You Can Trust
The MAG 2 Air is built around a safety architecture that addresses the full range of forces a rider encounters — from straightline braking to late-apex aggression. TPU impact protectors are positioned across the heel, ankle and toe box, while high-impact shields reinforce the zones most exposed in a slide. Systems designed to reduce rotational loading work in concert with flexible articulation areas, so your foot moves naturally through the full range of riding inputs without the boot fighting you. This is not generic sport-boot protection — it is a considered, layered system where each component has a defined role.
NUUN 002M 3-Stage Holding System
The NUUN 002M closure is one of the most compelling reasons to choose the MAG 2 Air over a traditional zip-entry racing boot. The three-point fixation system locks the boot precisely to your foot and lower leg, eliminating the micro-movement that erodes feel and accelerates fatigue on long stints. Fine adjustment takes seconds and can be made without stopping, so you can dial in the fit as your foot warms up during a session. Pressure is distributed evenly across the closure points rather than concentrated at a single buckle, which means all-day comfort alongside race-ready security.
Airflow Construction
A racing boot that traps heat is a boot that costs you concentration and performance. Sidi's airflow construction integrates a ventilated sole, breathable structural materials and dedicated ventilation channels routed through the areas that generate the most heat. The result is a boot that maintains its protective rigidity while allowing meaningful air exchange — a balance that conventional full-leather race boots rarely achieve. Whether you are completing back-to-back track sessions or riding to the venue in summer heat, the MAG 2 Air keeps your feet in a comfortable operating range.
Flat Inner Contact Surface
Professionals have long understood that the interface between boot sole and footpeg is where rider input begins. The MAG 2 Air's specially engineered flat inner surface maximises the contact area with the footpeg, giving you an unambiguous feel for peg position, a precise pivot point for gear changes and confident weight transfer through corners. Features like this separate a true racing boot from a boot that merely looks the part.
Sidi Impact Science and Sustainability
Sidi's product development sits within a broader commitment to responsible manufacturing. The brand aligns its production practices with the UN Sustainable Development Goals, pursues CO₂ reduction targets through the Science Based Targets initiative (SBTi) and selects long-lasting materials that reduce the need for frequent replacement. Choosing the MAG 2 Air means investing in a boot engineered to last, produced by a brand with a genuine sustainability strategy.

The Sidi MAG 2 Air is a universal-fit motorcycle racing and sport boot available in a full range of European sizes from 39 through to 47. It is suited to supersport, superbike and hypermotard riders, track day participants and performance road riders who demand certified protection at every outing.
