Technologies

Politex
The “politex” material is constructed of several overlapping layers with different physical-mechanical properties, the compacted PVC is then coupled to two fabrics (knitted fabric + felt) that is then is film dyed for long-lasting color retention. “Politex” offers strong resistance to ripping, laceration, stretching and fading. “Politex” is made in strict compliance with European regulations and is a totally “green” product.

Tecno-3
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.

Millennium 4 Carbon Composite Sole
The Millennium 4 Carbon Composite Sole features injected carbon fiber 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 aging, 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. These soles use 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.
