SiDi Kaos Road Cycling Shoe
The Sidi Kaos road shoe is the little brother of the SiDi Wire. Top perfomance at a great price. This pair of shoes is the right choice for those who can do without some details of the successfull Wire but who are looking for the same fit and quality. 
Direct power transfer via the robust and stiff Millenium 4 carbon sole. The Soft Instep 2 technology as well as the Tecno 3 closure system with additional ratchet provide comfort and best adjustment possibilities. 
  • MILLENIUM 4 CARBON SOLE: Composite sole (nylon matrix with carbon content)
  • TECNO-3 CLOSURE SYSTEM: Comfortable and ergonomic shoe closure system over the entire length of the shoe with nylon wire and twist closure. Precise adjustment even while riding. 
  • SOFT INSTEP 3 closure system: Anatomical ratchet strap for optimal adjustment and even pressure distribution on the instep. 
  • MICROFIBRE VERNICE material: Upper made of high-quality shiny microfibre material. 
  • COMFORT FIT insole: Slightly padded insole made of ergonomic foam with memory effect. 
  • REPLACEABLE HEEL PAD: Replaceable polyurethane heel. 


Millenium 4 Carbon Sole:

High-quality carbon reinforced nylon sole in a new carbon look. The optimised carbon fibre content provides excellent stability and yet a great comfort for the entire feet. An anti-slip, replaceable polyurethane heel pad offers comfort when walking. Cleat alignment mark for a perfect positioning of the cleats. Compatible with all common road bike pedal systems. 
Techno 3 System:
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.
Caliper Buckle:
This micrometric closure is adjustable by lifting the central buckle. In order to completely open, lift together both side buckles, or push the centre button to slightly loosen one tooth at the time. This allows precise and easy adjustment on the fly. 
Soft Instep Closure:
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 system is micro adjustable from both sides to perfectly centre the EVA pad over a high or low instep. The soft instep system is replaceable.
Sidi Heel Cup:
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.
Replaceable Heel Pad:
For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad.

Sizing Information for SiDi Shoes



I am a 1st time Sidi user, I wanted different brand other than Shimano and I believe I hit it right on. Setting up the cleats was fast and easy. Getting in and out of the shoes is much faster. The adjustments using the Techno Ratchet system is a great idea. Don`t really need the heel adjustment as the fit feels already good and comfortable especially on long rides. The carbon sole is stiff allowing better power transfer. All in all the Sidi Kaos is a very good road shoe, you can never go wrong with this shoe. I bit pricey but you don`t put a price on performance and comfort. I highly recommend this product.
Bought a pair of these in patent black as I already have a pair of Sidi Genius 5's and have been really pleased with them. The Kaos are even better as the different type of fasteners allow you to gain a better fit, which coupled with the carbon sole, makes them more comfortable and well worth the extra money. Theses are a great pair of shoes and I most definitely recommend them.
Excellent fit, comfortable adjustment, hassle free, I pair it with Look KEO Blade 2 carbon pedals
