The Sidi Kaos Air Road Shoe combines many of Sidi's class-leading developments in an affordable and stylish road cycling shoe with a vented upper for superb warm weather performance.
SIDI’s TECHNO-3 SYSTEM dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customized 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.
SOFT INSTEP CLOSURE SYSTEM
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. The SOFT INSTEP CLOSURE SYSTEM is adjustable from both sides, to perfectly center 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.
The micrometric closure called “CALLIPER BUCKLE” 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 cup that stabilises and supports the heel. Anatomically shaped plastic reduces heel slip and provides increased power transfer. Provides additional foot protection in the event of a crash.
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 10 mm lateral and fore/aft cleat alignment scale on the sole as well as the Look Memory Eyelet for easy cleat alignment and replacement.
