    Ride in a shoe that retains its durability and rigidity despite changes from aging, prolonged use and temperature changes. The SIDI Men’s Kaos Air Carbon Cycling Shoe features fabric that resists ripping, laceration, stretching and fading. This shoe will never disappoint.


    • 658g per shoe (size 45).


    • Vented Politex upper:
      • Politex material constructed of several overlapping layers with different physical-mechanical properties, the compacted PVC is then coupled to two fabrics (knitted fabric, felt) that are then film dyed for long-lasting color retention.
      • Offers strong resistance to ripping, laceration, stretching and fading.
      • Politex is a totally “green” product
    • Tecno-3 System dials fit along the entire length of the shoes, adapting the upper to the foot shape for a custom fit.
      • For closure, SIDI Wire material is completely non-binding for intuitive and effortless on-the-fly adjustments.
      • Tecno-3 buckle is serviceable and replaceable.


    • Millenium 4 Carbon Composite Sole
    • Injected carbon fiber in a Nylon matric, providing more rigidity than a standard Nylon shoe.
    • More durable, completely non water-absorbent and mechanically stable, meaning it’s less susceptible to changes in stiffness resulting from aging, prolonged use, and changes in temperature or humidity.
    • Anti-slip toe insert and replaceable Polyurethane heel pad are incorporated into the sole for walkability.
    • Uses a standard 3-hole drilling pattern for compatibility with the best pedal systems available.
    • Includes a printed 10mm lateral and fore/aft cleat alignment scale on the sole.
    • Look Memory Eyelet for easy cleat alignment and replacement.


    • Soft Instep Closure System:
      • Wide, anatomically curved strap combined with a soft, thermos-formed EVA pad that distributes pressure evenly over the instep area.
      • Adjustable from both sides to perfectly center the EVA pad over a high or low instep.
      • This system eliminates the need for the High Instep Extender and is replaceable.
    • Also adjustable during a race, the micrometric closure called “caliper buckle” adjusts by lifting central buckle—opens completely by lifting both side buckles together or pushing the center button to slightly loosen one at a time.
    • Reinforced heel keeps the foot in an optimal position and avoids the shoe being deformed by extreme performance or prolonged pressure.

More From SIDI

About This Brand


SIDI® was founded in 1960 by Dino Signori whose love for cycling steered the company away from mountaineering footwear to bike shoes. In Maser, Italy, SIDI was a pioneer, creating many features that either improved on the first bike shoe models or were the first.

The very first SIDI bike shoe was made with adjustable screws. Because of this, cyclists stopped nailing cleats into the bottoms of their bike shoes. Another innovation that SIDI started was creating a SIDI bike shoe that had a Nylon sole for durable stiffness. SIDI also created the first modern bike shoe that used Velcro® in place of laces. They were even the first to make mountain bike shoes with lugged rubber soles for improved stability and durability. They also innovated style when they were the first to have multicolored bike shoes on the outside and the inside with a 2-colored sole.

They are still improving on their SIDI bike shoes by continuously testing and studying research. This led to the birth of SIDI Aeronet Light, an aerospace material that allows some of the SIDI bike shoes to be 60 grams lighter without losing their shape or toughness. When you are cycling to get to the Kona Ironman® you know how every grams counts. Also, their SIDI High Security Velcro® piece was the first no-slip bike shoe strap ever made. SIDI has respect for the past, they are the last company that designs and makes their bike shoes in Europe, with their sights set on the future.
