The Sidi Kaos Carbon Cycling Shoes deliver all the standard Sidi details, with a high quality fit and design. The Sidi shoes feature a Millennium 4 carbon composite sole that provides more rigidity than a standard nylon sole. Soft Instep 2 and the Tecno-3 closure system provide a customised and adjustable fit for optimum comfort. - A.D.
Soft Instep 2 System: This system is a wide, anatomically curved strap combined with a soft, thermo-formed EVA pad that distributes pressure evenly over the instep area. The Soft Instep Closure System is adjustable from both sides, to perfectly centre the EVA pad over a high or low instep. The system eliminates the need for the High Instep Extender. The Soft Instep Closure System is replaceable.
Tecno-3 System: Sidi’s Tecno-3 System dials in the fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customised fit. Sidi’s famously reliable and replaceable closures are improved by an all new proprietary Sidi Wire material that is completely non-binding for intuitive and effortless on-the-fly adjustments. Like most Sidi small parts, the Tecno-3 buckle is serviceable and replaceable.
Caliper Buckle: The micrometric closure is adjustable by lifting the central buckle. In order to completely open, lift together both side buckles, or push the centre button to slightly loosen one tooth at the time. The system is also adjustable during a race.
Sidi Heel Cup: The reinforced heel keeps the foot in a optimal position and avoids the shoe being deformed by extreme performance or prolonged pressure. For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad.
Millennium 4 Carbon Composite Sole: The Millennium 4 Carbon Composite Sole features injected carbon fibre in a matrix of Nylon, providing more rigidity than a standard nylon sole. The Millennium 4 Carbon Composite Sole is also more durable, completely non water-absorbent and mechanically stable, meaning it’s less susceptible to changes in stiffness resulting from ageing, prolonged usage, and changes in temperature or humidity.
An anti-slip toe insert and replaceable polyurethane heel pad are incorporated into the Millennium 4 Carbon Composite Sole, for walkability. The Millennium 4 Carbon Composite Sole uses a standard 3-hole drilling pattern for compatibility with the best pedal systems available, and includes a printed 10mm lateral and fore/aft cleat alignment scale on the sole as well as the Look Memory Eyelet for easy cleat alignment and replacement.
Please Note: All buckles and mechanisms are replaceable.
