The Sidi Mag-1 Air has all the same features as the Mag-1 with the addition of a perforated outer for maximum air flow. The Sidi Mag-1 Air Boots feature an innovative internal brace system constructed from carbon fiber for the ultimate in support and light weight design. The Mag-1 Boots weigh in at 4.4 pounds each, or 17% less than the Vortice boots. An all new Micrometric Tecno 3 magnetic closure system makes adjustments quick and easy and the internal brace system provides ankle stability and flexibility. The rear upper is made in polyurethane and is assembled to the boot with two screws: one on the outside under the TECNO-3 Magnetic mechanism, the other on the inside which holds the micrometric adjuster strap. The screws support and block the internal support system which is made with carbon fiber beams, making up the frame of the boot. This system allows excellent flex movement front-to-back while being firm side-to-side. An all new Micrometric Tecno-3 magnetic closure mechanism is easy and quick to use as well as being highly adjustable and light in weight. The TECNO-3 Magnetic closures close the boot with an extremely resistant steel wire, that is hooked to the clip with the aid of a magnet. Sidi has created an incredibly solid boot with well-chosen design elements and materials to create a very lightweight, yet ultra-protective race boot system.
