Find comfort in the chaos.
The Kaos shoes are built upon the Millenium 4 Outsole, which is a nylon matrix infused with carbon fiber. The mixed compound is resistant to heat and humidity, ensuring that your soles will outlast replacement heel pads and buckles, which are available separately.
The uppers are a breathable synthetic leather lined with a microfiber to keep your feet cool and dry. Unlike leather, the synthetic will not stretch and provides consistent support for your feet. To secure the shoes, Sidi placed its ratcheting buckle at the ankle sewn to a wide band to reduce pressure. At the forefoot are two Techo-3 buckles. These feature a twist and tighten mechanism that allows micro-adjustments. Both are easy to adjust in the saddle.

Sad about Sidi
- Familiarity: I returned this product before using it
- Fit: Runs large
- Size Bought: 45.5
I too have worn Sidi shoes for yrs. I should have believed the reviews on size! I ordered the same size I currently wear (45.5) and the new shoes were not only much longer, but wider as well. The material was starting to "bunch up" as I tightened the buckles. I was also a bit disappointed in the feel and look of the material. It felt very "plastic" like. Not sure I would have kept them even if the fit was right. I was expecting a better "feel" for a shoe that is supposedly worth $300.
SIDI - consistency
- Fit: True to size
I always find SIDI to be the most consistent in build and size from generation to generation. This shoe here is the Ultegra of Shimano, it has just about everything DA has but half the price. The material will stay white for long time and there is very little fabric that will turn yellowish over time around the ankle. With a little soap the fabric can be kept flat white for a long time also. Just like every other SIDI you don't buy new ones because you wore out the old ones, these things last. I have SIDI's from 10 years ago still look great. Money well spent.
Everything I expected and wanted
- Fit: True to size
- Size Bought: 46.5
As a long-time Sidi user, I wanted a more customizable fit than I had had with the Genius 5 - which I loved and used for 10 years. I have a high instep and a "bump" on the top of one foot, so sometimes the mid-foot straps would generate uneven pressure and occasional discomfort on longer rides. The Techno 3 ratchet system seemed a great idea, so first I tried the Wire Vent Carbon shoe. Because of my high instep and the Techno 3 top buckle which restricted my ability to open the shoe fully, I had trouble getting into the shoe. I then tried the Kaos, which uses the more traditional caliper buckle on the top and the Techno 3 ratchet system for the mid-foot and toe. As I had hoped, the Techno 3 system applies an even pressure across the entire top of the foot - even where my "bump" has caused discomfort in the past. The ratchets can be dialed tighter or looser with great precision. The top caliper buckle enables me to open fully and get into the shoe easily, and when tightened it holds the top of the foot snugly and comfortably. The upper is supple and quite comfortable as well. The sole is stiff allowing for an efficient transfer of power. My only unfulfilled wish is that the Kaos doesn't have the Adjustable Heel Retention Device that the Wire Vent Carbon had - a terrific feature. All in all however, this is a great shoe, and it delivers everything that I had hoped for in a high quality (and, yes, expensive) road shoe.
Nice looking shoe but had fit issues
- Fit: Runs large
Try this on before you install the cleats. My experience may a fluke but I had some issues with discomfort that I have not experienced with any other Sidi shoes. To begin, the polished appearance is nice. The fastening system is also really nice. The top position is tightened with a user-friendly ratchet buckle. Below that, a single wire-type dial can be rotated to tighten the 2nd and 3rd position, which is convenient (2 adjustments rather than 3). However -- the tongue felt sharp and high, and it cut into my ankle. I thought it might break in after a few rides, but no - I had to wear thick socks to protect my ankle from the sharp tongue. The overall fit felt deeper than my Genius 6.6, and the sole I think is also thicker than my 6.6 that I was replacing, so I had problems getting comfortable with these, and I ended up switching to another shoe.
I highly recommend these shoes.
- Familiarity: I've put it through the wringer
- Fit: True to size
My carbon road shoes have 4K miles on them, so I thought I'd move them to wet weather shoes and buy a replacement for routine use. After some research, I thought that the Sidi Kaos had great value for the construction, manufacturer reputation, and, frankly, looks - for a great price. I ordered a 44 and a 45, because that's what I wear depending on the manufacturer. These run a little on the larger size, so the 45's were perfect. First ride was ~50 miles and they were comfortable, stiff, and very easy to adjust for the perfect cleat placement on the ride.
Are these spdcompatible?
These shoes are set up for the SPD-SL road cleats but if you are talking about the SPD mountain cleats those will not work. Any cleat with the 3 hole adapter.
Do they make Mega sizes anymore? Looking for 46.5 Mega in fluo
The Genius 6.6 Vent is the only Sidi we have available right in a wide fit. Let me know if you have any other questions. firstname.lastname@example.org
Are these available in a size 42 Mega for wide feet?
Second that question! Mega size please?
