This innovative material is also water-resistant, durable, and does not lose its shape with use or changes in temperature and humidity.

Offers protection, comfort and easy to clean

A synthetic material makes up the top of the Sidi Kaos. The shiny material offers protection against the elements. As a bonus, the smooth surface makes it easy to clean and maintain.

Sidi Kaos Protective upper

Perforation vents are present on the vamp and quarters. They aid in heat dissipation and moisture regulation. The inside is covered in a soft cloth that helps in moisture regulation and prevention of hot spots.

Secure wrap

The Kaos uses two types of locking mechanisms: the TECNO-3 SYSTEM and the caliper buckle. The caliper buckle works with the soft instep closure, which is a broad strap that evenly distributes pressure on the instep. The strap can be adjusted on both ends, so the foam pad is centered.

Sidi Kaos Secure wrap

As for the TECNO-3 SYSTEM, it ensures a secure wrap with a turn of the dial. The buckle has buttons on the side which can be used for micro-adjustments to achieve optimal foothold and comfort.

Thin foam insole

A thin foam insole lines the inside of the footwear. It prevents the foot from sliding inside while pedaling to avoid chafing and blisters.
