Sidi Kaos roadracing shoes

Tecno 3 Precision Ratchet closure independently micro-adjust fit across forefoot and toe and is serviceable and replaceable

Caliper Buckle two-way ratchet for easy on-bike adjustment with incremental tightening and loosening

Soft Instep 2 System distributes pressure evenly over the arch area and is adjustable from both sides to achieve the perfect center position. Eliminates the need for the High Instep Extender and is serviceable and replaceable.

SIDI Heel Cup stabilizes and supports the heel to reduce slippage and increase power transfer

Replaceable heel pad securely closes the back of the shoe around the heel and above the heel bone eliminating heel lift and increasing how much leg power is harnessed

Millennium 4 Carbon Sole:

Made of Nylon injected with carbon fiber that makes it 37% stiffer than the traditional nylon sole

Provides excellent power transfer

Has enough flexion so blood circulates and the foot doesn't cramp.

Lasts through many miles of riding under all conditions because it doesn't absorb moisture and resists deterioration that can be caused by high mileage or extreme temperatures.

Uses a 3-hold 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.
