The SiDi Ergo 3 is the newest addition to
SiDi's leading Road Cycling shoe range.
Replacing the Ergo 2, this new model is
offered with two soles that have never
before been released onto the market.
Vent Carbon Sole SiDi
introduces a newly re-engineered and lighter
racing sole. There is an added vent inserted
at the very top of the sole, which when
open, gives godd ventilation. Air will flow
though predisposed channesl until an exhaust
located towards the middle of the shoe. This
new technology invovled SiDi modifying the
removable insole and footbed of the shoe,
but the result is a giant leap forward for
professional cyclists. The Air-Vent can be
opened or closed as needed.
Carbon Sole has been developed to assist
with blood circulation by further advancing
the technology behind the power transfer
ability inherent in the design of SiDi
Shoes. These soles are built to give light
flex towards the nose of the shoe whilst
maintaining an excellent level of stiffness
thoughout the shoe's body.

includes a replacable polyurethane heel pad.
This new sole is also compatable with all of
the best pedals on the market and to
facilitate cleat replacement, the Vent
Carbon Sole features a 10mm horizontal and
vertical cleat alignment scale moulded into
the sole itself. Finished with the Look
Soft Instep Closure System
The wide, anatomical and
padded strap has been reduced and coupled to
soft, thermo-formed material increasing
comfort and performance. It distributes
pressure evenly over the arch area,
adjustable from both sides for perfect

frontal micrometric closure and adapts the
upper of the shoe to the shape of the foot
for a customised fit. The Tecno II system is
now smaller and can be replaced more easily.
Serviceable and replaceable.
Velcro Security System High security Velcro with integrated locking polymer teeth that engage onto each other when the strap is closed. This feature makes the closure more secure and the Velcro becomes unmoveable.
Adjustable Heel Retention
technology for the heel cup system. The
adjustable heel retention device reinforces
the top of the heel cup and improves fit by
closing the back of the shoe more securely
around the rider’s ankle. The heel retention
device tightens the top of the heel cup so
that it doesn’t slip during steep climbs or
sprints. It can be adjusted with two small
screws that work independently from each
other. For a custom adjustment turn the
screw towards the + sign to tighten the heel
retention device and towards the – sign to
spare part that prolongs shoe life way past
that of the competition.
