SIDI Kaos Air Carbon Road Shoes
These shoes features perforations in the upper material to improve air flow. This material is called politex, and it's constructed of several overlapping layers. The Kaso Air's Millennium 4 carbon sole has injected carbon fiber in a nylon matrix to provide more rigidity than a regular nylon sole, but at the same time is a bit more comfortable than a full race carbon sole.
Kaos Air also has Sidi's Tecno 3 precision ratchet closures so you can independently micro-adjust the fit across the forefoot and toe area. 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. Important details include the reinforced heel that keeps the foot in an optimal position and avoids the shoe from being deformed by hard efforts or prolonged pressure. And for walkability, the shoes include replaceable polyurethane heel pads.
