The SIDI Kaos Shoe has a stiff sole and a stiff heel which serve as the platform that directs leg power from rider to pedal. The combination of stiff structure, along with the multiple adjustments the rider can make for a custom fit, create a cycling shoe that efficiently converts leg power to bike speed.

The Kaos shoe is durable--- it keeps its shape in wet, dry, cold or warm weather. The Kaos, like all SIDI shoes, has many replaceable features. SIDI cycling shoes have been known for years for their stiff soles. SIDI
