The SOFT INSTEP CLOSURE SYSTEM is a wide, anatomically curved strap combined with a soft, thermo-formed EVA pad that distributes pressure evenly over the instep area.
The SOFT INSTEP CLOSURE SYSTEM is adjustable from both sides, to perfectly center the EVA pad over a high or low instep.
The system eliminates the need for the High Instep Extender. The SOFT INSTEP CLOSURE SYSTEM is replaceable.
SIDI’s TECNO-3 SYSTEM dials in fit along the upper part of the feet for a customized fit. SIDI’s famously reliable and replaceable closures are improved by an all-new proprietary SIDI Wire material that is completely non-binding for intuitive and effortless on-the-fly adjustments. Like most SIDI small parts, the TECHNO-3 PUSH buckle is serviceable and replaceable.
It can be adjusted while riding, thanks to an innovative button that can be pushed to lift the buckle and facilitate the adjustment.
The central mechanism, SINGLE TECNO-3 PUSH SYSTEM, creates a perfect tension balance between the shoe’s internal and external side.
The symmetrical mechanism guarantees an excellent closure adapting on every instep.
An innovative button added to the monofilament buckle, if pushed, lifts the buckle to facilitate the adjustment.
The ADJUSTABLE HEEL RETENTION DEVICE reinforces the top of the heel cup and improves the fit by closing the back of the shoe securely around the rider’s heel. The heel retention device tightens the top of the heel cup so that the heel doesn’t slide out during steep climbs or sprints.
Each side of the heel can be adjusted independently, for a perfect fit.
For a custom, adjustment turn the screw towards the + sign to tighten the heel retention device and towards the – sign to open it.
Lightweight, easy to use, and replaceable.
Reinforced cup that stabilizes and supports the heel. Anatomically shaped plastic, reduces heel slip and provides increased power transfer. Provides additional foot protection in the event of a crash.
For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad. WIRE’s heel pad has a new design and it is very light.
The key benefits of the VENT CARBON Sole are not only superior power transfer, because of its light weight and stiffness, but also warm weather comfort.
The VENT CARBON Sole is designed with an integrated vent and air channels for heat dissipation and air flow. The vent can be opened or closed for 4-season comfort.
The VENT CARBON Sole is handmade exclusively of carbon fiber in a weave pattern oriented at opposing angles that maximize stiffness while allowing for a small degree of controlled flex in the toe area. This carefully designed flex biomechanically relieves stress on the plantar tendon and helps promote circulation.
The VENT CARBON Sole features a standard 3-hole drilling pattern, printed 10 mm lateral and fore/aft cleat alignment scale as well as the Look Memory Eyelet for easy cleat alignment and replacement.

Sidi Size Guide
*Customers switching to Sidi Shoes or from Sidi;s more than 5 years old, may not wear the same size. All Sidi's, except for winter shoes, are built on the same last, but differences in patterns and materials so keep this in mind when switching between Sidi models. Every Sidi Shoe (except triathlon models) from 2002 onwards is stamped with its size and last type (and M indicates Mega or W indicates women's), Usually on the tongue.
Standard Width is considered as a D width
Mega = EE shoe fit 4mm of extra space across the ball of the foot. If you have high-volume orthotics you may feel more comfortable in a mega shoe.
Women fits - "Women specific" shoes are a narrower and smaller version of the regular fit option. The heel and ankle areas have also been narrowed.
How do I know if its a good fit?
Some people have narrow heels, if you know this to be true we recommend getting a shoe with a heel retention device. This will allow the heel to be narrowed.
Is it too small? If you stand up with your shoes on and your toes are touching the front, your shoe is small. You don't want any toes touching the front of the shoe, this will create hot or numb toes on long rides. You want to be able to wiggle your toes a bit, but not feel like they are "sloshing around"
Tip* Try on your new Sidi Shoes with the cycling socks you normally wear
If the shoe doesn't fit? Don't worry, we offer a 1 free resize policy to make sure you are very comfortable on your bike
