'While a lot of other boots sport flashy knickknacks that don't have
much substance, the new Sidi Vortice's features have all been designed
with rider protection in mind, with input from orthopedic doctors as
well as racers. It was difficult to imagine Sidi improving upon the
Vertigo Corsa, but they've managed to do just that with the new

The gear change shifter pad is molded of DuPont Techno-polymers, which
ensure that the plastics qualities will not change in high or low
temperatures. Sidi boots deliver a strong, consistent feel when you
grab the shifter and blast through the next gear.
The Vertigo and Vortice series of 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
with micro adjustments that deliver a perfect fit. A maximum adjustment
of 5cm is provided.
Vortice and Vortice Air boots extend the adjustable calf system, by
incorporating the Tecno-II buckle system over the bridge of the your
foot. With a simple adjustment of the Tecno knob, the internal
monofilament line will evenly close and wrap the boot around your foot
in micro adjustments for a perfect glove-like fit. This system prevents
your foot from sliding forward in a crash, thus offering extra
protection to your toes.
The three stage, shock absorbing heel cup is molded in three different
densities of plastic that sets the Vertigo and Vortice series apart
from all other sport boots. This system offers a built in shock
absorbing range of 3mm. The heel cup's internal area is also fully
lined with impact resistant thousand-air cell memory foam for and extra
level of comfort and protection.
Air Vent System
Both the Vortice and Vertigo employ an air ventilation system that can
be opened or closed with a touch of a button depending upon your needs.
This Malleable guard on the outer edge of each boot also protects the
small and vulnerable foot bones. The Vortice also features a close-able
air vent system on the toe as part of the toe slider system.
The Vortice's exclusive external ankle brace system ties into the
calves Tecno VR panel and the boot lower in order to provide the
highest level of support against torsional twists or severe impacts
without reducing the boot's flexibility or comfort. Made of Nylon based
thermoplastic resins, the material offers high resistance and
protective qualities. Please note that the external ankle brace is
provided on the inside AND outside of the rider's ankle with each
New elastic panels adjacent to the entry zipper allow a bind free zip
and improved fit. This makes it easier to put the boot on, take it off,
and helps extend the life of the boots significantly.
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 foot peg pressures.
Every bolt on component is available separately. If it's a part you can
remove, it's a part we can replace. You can change the various
components to replace items that have worn or damaged in a crash.
Every Vertigo or Vortice boots outer is made with Lorica. 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. We inject
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. Lorica is also highly resistant
to abrasion, yet it still breathes, with more than three million pores
per square centimeter. Easy to maintain, Lorica doesn't stain, can't be
scratched and offers reduced weight, more flexibility and a better feel
than leather racing 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 transferred 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
