SiDi Kaos Road Cycling Shoe


The Sidi Kaos is a great choice of road cycling shoe if you’re looking for an affordable shoe which benefits from the same cutting-edge technology and manufacturing techniques used higher up in the range. Regarded as the little brother of the Sidi Wire shoe the Kaos offers the same fit and feel of its more expensive brother as well as that iconic Italian styling synonymous with the Sidi brand. Featuring a Millenium 4 carbon composite sole with injected carbon fibre in a matrix of nylon to give more rigidity than a standard nylon sole the Sidi Kaos shoe provides superior power transfer through to your pedals while the sole of the shoe is fitted with the standard 3-hole drilling pattern making it compatible with the majority of pedal systems including the Shimano SPD-SL and the Look Keo. Off the bike an anti-slip polyurethane toe and replaceable heel inserts make walking easier and safer.

Sidi have combined a Micro caliper buckle with a twist dial and nylon wire closure to provide a comfortable and ergonomic Techno 3 closure system over the entire length of the top of the foot, allowing you to fine tune fit even when on-the-fly while avoiding unwanted pressure points thanks to their anatomically curved Soft Instep 3 strap with a super-soft EVA pad. Sidi have included a reinforced cup on the Kaos cycling shoe to support your heel and prevent any potential for heel lift when you’re out of the saddle putting the power down.



  • Millennium 4 Carbon Composite sole
  • Replaceable heel inserts
  • Techno 3 closure system with Micro Caliper buckle & twist dial
  • Soft Instep 3
  • Microfibre Vernice upper 
Nice fitting shoes, great power transfer
Decided to splash on Sidi after current pair of Shimano shoes fell apart. I have found that the reputation of this manufacturer for quality and style is fully justified. I have a narrow foot and the infinitely adjustable ratchet and Tecno 3 system allows perfect fit. I take a 8.5-9 UK shoe and bought a 44 which is perfect length. First wore them on a very hot day, just a 30 mile spin but very pleased with them.
Excellent product, look great and fit perfect. Outstanding price which is always the norm at Merlin. I now have 5 pairs of Sidi shoes! As my wife often reminds can never have too many pairs of shoes!
Good quality and better ventilation then the Level model that I have previously.
Fabulous shoes, bought a half a size bigger than usual, a great shoe, nice and stiff, very comfortable
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
