Kaos Air Carbon Cycling Shoe
If you're looking to stay on this side of the $400 price point when you buy your next pair of cycling shoes, you've probably drooled over plenty of pricier pairs in your search, mourning the impossibility of buying them. Stop moping, and stick your feet into in Sidi's Kaos Air Carbon Shoes instead to stay on-budget without sacrificing the sleek functionality of pricier options.
Sidi shoes have been a mainstay both in the peloton and amongst the well-shod feet of professional amateurs for decades now, and the Kaos Air is a model that's continued to improve over the years, this year boasting added breeziness from Air uppers. You'll avoid slimy toes on hot, sunny rides while your foot stays locked-in with the Kaos' innovative combination of a Tecno 3 buckle and a main ratcheting buckle. Make as many adjustments as you want before or during a ride with the system, which allows for nearly unlimited fit tweaks. A plush, padded instep will ward off pressure points and restriction, and once you dial the Tecno-3 buckle into the position you want, the non-binding and non-stretch wire won't gradually inch out of position during your ride. Underneath your foot, Sidi graced the Kaos Air with its Millenium 4 Carbon Composite outsole, which consists of nylon blended with carbon fiber and allows the shoe to maintain its relatively accessible price point without sacrificing a stiff, reactive platform for power transfer.
- Millenium 4 Carbon Composite outsole
- 1 Tecno-3 wire dial and 1 ratcheting buckle closure

A step up in gear
I first bought a size 45 because that is what fits me in every piece of footwear I've worn in my adult life. They were quite small and I returned them. With the right size these shoes are clearly superior to any I've had in 40 years of cycling. They feel comfortable and I think they are very good looking.

I have two pairs of these one for zwifting, the other for road riding. I have to say that these fit me very well. I have a low foot volume with fairly narrow feet, these SIDI's are a perfect fit for my foot shape/type. They also look good and are reasonably easy to clean.

Shoes are lite, very comfortable, and in hot weather they breathe so much I feel air while peddling. Fit is better than expected.

Perfect Fit & Comfortable
These are the best shoes I've owned. They are a perfect fit, and the wire tightening system is amazing. The entire upper part of the shoe becomes form-fitting with a slight turn of the dial, which can easily be done on the ride. The tongue is somewhat customizable on these, so you've got to follow the instructions and trim a small portion. That's not a big deal, and in fact I liked it because if it wasn't designed that way I'd never take a blade to a $300. pair of shoes and would have just lived with however the tongue felt against my leg. I'd highly recommend these and would definitely buy them again.

So far so good, comfortable footbed which was the main goal for me, my old Shimano's caused numbness within 10 miles or so, the stiff Kaos footbed fits me better and distributes the pressure much more evenly, it's an amazing difference even after 50+ miles. What is incomprehensible to me is the top of the tongue which is too long, with "teeth" that cut into my leg. The grooves that Sidi cuts into the last half inch of the tongue actually cause the tongue to curve downward, even with higher socks there is a constant "sawing" motion just above the ankle on the lower leg. Just a flat-out design flaw, luckily the padding of the tongue is not present here so I'll be able to cut this part off with an exacto knife. Not a huge deal, the rest of the shoe performs very well, but for $300 this is a major annoyance. From a purely aesthetic POV, the glossy white finish of the uppers is a bit much. I like the perforations and airflow, the graphics are nice, but matte white would have toned it all down nicely.

The tongue is meant to be cut to fit your foot, so it's not surprising that you were uncomfortable until you did so... Sidi doesn't mention this in their instruction manuals for some reason.

Exactly my experience Paul, regarding the saw-tooth tongue. Someone commented that you are supposed to cut that part, but I never had that issue with any prior pair of Sidi. Never, ever, ever before did I have a Sidi shoe with a saw tooth tongue and never did I hear you are supposed to cut them. Why design a shoe where you have to modify/cut it, straight out of the box??

Sidi Kaos Air
I made the swich from a pair of Lake mountain clipless shoes to the Sidi Kaos Air (size 48). I am a pretty big guy, 6'3'' 185 lb. The shoes fit great and the carbon composite sole effectively transfers my effort to the pedals. The ventilation from the Air upper is great and my feet don't get soggy with sweat. These shoes were worth the price, especially when I got them during the July 4th 20% off sale!

The shoes are great. They are true to size and deliver max power to the pedals. Could not be happier. Will purchase again.
