Sidi manufacture what many consider to be the worlds greatest motorcycle boots. Their impressive range of boots is technically advanced throughout, from the way the sole is manufactured, to the consideration of ventilation points.

Featuring more of the same innovative technology that made Tecno adjusters (for a very precise fit) a similar strap across the bridge of the foot now restrains forward movement and reduces potential crush damage to toes in the event of an impact. There is also a new shock absorbing heel cup which is capable of moving on its mounts slightly in a crash, further reducing forces to the heel. These additions run alongside the usual assortment of safety features found on high-end race boots.

Sidi have raised the bar yet again with the introuction of the Vortice.

Specifications -

• Tecno Calf Tensioner, Tecno Shin Tensioner and Ankle Support System - This group of features ensures a very precise fit with maximum comfort.
• The Tecno Calf Tensioner mechanism adjusts the leg circumference. Fitted in the back of the boots upper, it works through a nylon wire that hooks directly into the shin plate. The Tecno Calf Tensioner is replaceable and is designed to fit around various sizes of calf muscles.
• Racing SRS Sole - This totally new feature from Sidi is constructed from a polyurethane and rubber blend. It features a removable insert in front of the arch area where the main wear and tear would eventually occur. Another patented exclusive from Sidi.
• The composite inner sole of the Vortice resists 'side to side' compression offering greater protection compared to the leather inner soles that many of Sidi's competitors use.
• Tecno Instep Tensioner - The Vortice features an additional fastening system on the front part of the foot, on the instep. It consists of a 'wrap around' facia which can be precision adjusted by the Tecno Instep Tensioner. This has proven critical to the riders safety after studies performed on previous motorcycle boots.
• The Sidi Vortice is constucted of Lorica and is lined wth Teflon vented mesh. The lining in the toe area is Cambrelle, a soft yet strong lining. Only Sidi goes to the trouble (and the expense) of creating a multiple liner boot system in its racing boots.
• Lorica is a composite micro-fibre 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 fibres act like natural leather skin, but with the addition of better strength, softer texture, lighter weight and better moisture protection. Lorica is also highly resistant to abrasion  - yet it still breathes - with more than 3 million pores per square centimeter.
