ERGO 4

CARBON COMPOSITE

MICROFIBRA TECHPRO is a microfiber PU Made in Italy. It is considered a highly technological and innovative, eco-friendly leather suitable for technical and sports products which require high performance levels. TECHPRO MICROFIBER incorporates features of resistancy, stability, lightness, water-repellency and eco-friendliness. 

TECHPRO MICROFIBER has a Hydro and anti-mold treatment, which eliminates the onset of molds and bacteria. TECHPRO MICROFIBER is Oeko-Tex certified, does not contain harmful substances and respects law restrictions.

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 PUSH 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 TECHNO-3 PUSH buckle is serviceable and replaceable. It can be adjusted while riding, thanks to an innovative button which can be pushed to lift the buckle and facilitate the adjustment.

HIGH SECURITY VELCRO straps with integrated locking polymer teeth, that engage onto each other when the strap is closed. This feature makes the closure more secure and the strap becomes unmoveable. 

The reinforced heel keeps the foot in a optimal position and avoids the shoe being deformed by extreme performance or prolonged pressure.

TWELVE CARBON COMPOSITE sole is made with two different materials blended together, nylon and carbon fibre. It is made out of injected Carbon Fiber in a matrix of Nylon. The Nylon used doesn’t absorb water and doesn’t lose rigidity in hot or humid weather or as it ages. The result is a significantly lighter and stiffer sole.


Sidi sizing 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
