The Vertigo boots are the only boots that offer the patented Tecno VR adjustable calf system, designed to accommodate calves of virtually any size in a clean, supportive and protective design. With a simple adjustment of the Tecno knob, the internal monofilament line precisely closes and wraps the boot around your calf witn micro adjustments that deliver a perfect fit. A maximum adjustment of 5cm is provided.

The composite inner sole of Sidi boots resists side to side compression, offering greater protection compared to the leather inner soles that our competitors use. The insole features a removable arch support and will never lose its dynamic characteristics, even after months of intense use. It's also water resistant and is designed to withstand high footpeg pressures.

When constructing most Sidi boots Sidi uses its own proprietary material called "Sidi Technomicro". (Sidi uses top grain leather with all Gore Tex membrane equipped models). Technomicro is a composite micro fiber material created from strands that are so fine, each one is less than one thousandth the thickness of silk. Sidi then injects it with special resins, so these fibers act like natural leather skin, but with the advantage of better strength, softer texture, lighter weight and better moisture protection. Technomicro is also highly resistant to abrasion yet it still breathes with more than three million pores per square centimeter. Easy to maintain, Technomicro doesn't stain, can't be scratched and offers reduced weight, more flexibility and a better feel than leather or other synthetic material boots.

Each Vertigo and Vortice series boot is lined throughout with lightweight perforated Teflon treated fabric in order to allow moisture to "breath". This moisture is quickly transfered to the Lorica outer, which manes it dry quickly with no mold build up in the long term. Additionally the inner ankle area of all Vertigo and Vortice series boots are fully lined with Sidi's secret formula of perforated closed thousand-air cell memory foam. The result is a totally breathable lining system.
