This brace allows excellent flex movement front-to-back while being firm side-to-side. The rear-upper features a soft red TPU-plastic to prevent the system pushing in your calf. The newly fitted closure system called "Tecno-3 Magnetic" makes sure the boot will perfectly fit by its precise adjusting. It is quick and easy in use due the magnetic closure helping you close the boot with one hand only. The magnets will stick on the boot in order to keep the closure in place. The boot folds together which makes a zipper superfluous.
The ankles of the boot are smooth and flat inside for more adherence with the bike and feature a replaceable shock absorbing system in the back and outside. The boot is made of synthetic leather and is triple-stitched on the high-stress areas. The arch and Achilles areas are covered with Sidi’s exclusive elastic textile and injection molded polyurethane comfort panels.
The inner lining features a honey-membrane made from Teflon and nylon which fold around the calf and ankles. The lower part of the boot has a Cambrelle lining. The Toe slider is made from nylon reinforced with fiberglass and features a air intake and alloy insert. The Calf of the Mag-1 can accommodate riders with up to an 35cm calf diameter when measured 25cm up from the bottom of the heel.
Just like all other Sidi boots all parts of the Mag-1 can be replaced. 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.
The Mag-1 is 17% lighter than the Vortice
