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 TECHNO-3 SYSTEM dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot 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 TECNO-3 SYSTEM is serviceable 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.
The MILLENNIUM 4 CARBON COMPOSITE Sole features injected carbon fiber in a matrix of Nylon, providing more rigidity than a standard nylon sole.
The MILLENNIUM 4 CARBON COMPOSITE Sole is also more durable, completely non water- absorbent and mechanically stable, meaning it’s less susceptible to changes in stiffness resulting from aging, prolonged usage, and changes in temperature or humidity.
The MILLENNIUM 4 CARBON COMPOSITE Sole uses a standard 3-hole drilling pattern for compatibility with the best pedal systems available, and includes a printed 10 mm lateral and fore/aft cleat alignment scale on the sole 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
