The Sidi Kaos Air Cycling Shoes offer everything followers have come to expect from Sidi with a high quality fit and technically advanced design. The Sidi shoes feature a Vent carbon sole with air intake that provides more rigidity than a standard nylon sole. Soft Instep 3 and the Tecno-3 push closure system provide a customised and adjustable fit for optimum comfort.
Soft Instep 3 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 an 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 and a comfort fit insole.
An anti-slip toe insert and replaceable polyurethane heel pad are incorporated into the Vent carbon sole, for walkability. The Vent carbon 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.
