The Motorcycle Boots SIDI Vertigo 2 are high-quality road/racing motorcycle shoes made of first-class Technomicro synthetic leather. The Tecno 3 Iron calf tensioner was patented by SIDI itself. This system consists of fine steel fibers which go through the two side holes. By tightening the fibers, you symmetrically tighten the boot around your calf. The ventilation system consists of a suction vent which you can open/close by pushing a button.
The heel shock absorber provides maximum protection. The heel of the Vertigo boots features a polyurethane shell with two shock absorbers. The shell can move by 3mm on impact. The Teflon-lined, breathable insole with air vents provides maximum comfort and prevents water and sweat absorption. As a result, the Motorcycle Boots SIDI Vertigo 2 dry fast, preventing mold growth.
