The Sidi Vertigo series of boots is the top selling road boot collection in the USA, and for good reason! Besides the standard version of the Sidi Vertigo, which is available in four attractive colors, there is a water resistant version aptly called the Vertigo Rain which is complemented by its warm weather cousin the fully vented Vertigo Air. New for 2008 is the spectacular Vertigo Mega Gore Tex. Mega means it features triple E width as well as a larger circumference around the whole foot. The legendary Gore Tex membrane is encapsulated in a top grain leather outer shell for a 100% waterproof wide boot, one of only two in the USA!

• Constructed of Lorica and is lined with Teflon vented mesh. Only Sidi goes to trouble and expense of creating a multiple liner boot system in its racing boots. Lorica® is a composite micro fiber material created from strands that are so fine, each one is less than one thousandth the thickness of silk. When injected with special resins, these fibers act like natural leather skin, but with the addition of better strength, softer texture, lighter weight and better moisture protection.
• Sidi has added a small elastic panel to aid in a smooth zipper operation as it allows a bit of movement via the elastic as the zipper passes over the rider’s ankle ball.
• The rear upper part of the boot is made up of the following mechanisms:
• The Tecno Calf Tensioner mechanism adjusts the leg circumference. Placed in the back of the boots upper, it works through a nylon wire that hooks directly to the shin plate
• The Tecno Shin Tensioner mechanism helps the Tecno Calf Tensioner close the leg upper on the front part of the boot. The two lateral nylon braces join the ankle joint with two screws that are protected by nylon caps. This system is reinforced with fiberglass, supports the ankle and is easy to replace. This system allows excellent flex movement front-to-back while being firm side-to-side
• Tecno Instep Tensioner, a fastening system on the front part of the foot, on the instep
