SIDI Shoe Kaos Air

MILLENNIUM 4 CARBON COMPOSITE

The Millennium 4 Carbon Composite Sole features injected carbon fiber in a matrix of nylon, providing more rigidity than a standard nylon sole. The sole is also more durable, completely non-water-absorbent and mechanically stable, meaning it’s less susceptible to changes in stiffness resulting from aging, prolonged usage, and changes in temperature or humidity. An anti-slip toe insert and replaceable polyurethane heel pad are incorporated into the Millenium 4 Carbon Composite Sole for walkability. It 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. The Air model features a fully perforated upper to give greater ventilation for those riding in warmer conditions or climbing; or simply for those who experience hot feet whilst riding.

SOFT INSTEP CLOSURE SYSTEM

The wide, anatomical and padded strap has been reduced and coupled to soft, thermo-formed material increasing comfort and performance. It distributes pressure evenly over the arch area, adjustable from both sides for perfect centering. Used with Caliper Buckle straps, it is serviceable and replaceable.

CALIPER BUCKLE

The micrometric closure called “Caliper Buckle” is adjustable by lifting the central buckle. In order to completely open, lift together both side buckles, or push the center button to slightly loosen one tooth at the time. The system is also adjustable during a race.

TECNO-3 SYSTEM

Sidi’s Tecno-3 System dials in fit along the mid and forefoot sections 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 System is serviceable and replaceable.

HIGH SECURITY VELCRO

High Security Velcro straps with integrated locking polymer teeth, that engage onto each other when the strap is closed. This feature makes the closure more secure and the strap becomes unmovable.

REPLACEABLE HEEL PAD

For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad.
