This is the Sidi Alba Men's Carbon Road Cycling Shoe. An entry level road bike shoe in the Sidi lineup, packed with all the great traditional Sidi quality and construction. Featuring the Millennium 4 Carbon Sole, Tecno 3 Precision ratchet closure with two hook and loop straps, external reinforced heel cup, and replaceable heel pad. 

Millennium 4 Carbon composite sole: 
featuring injected carbon fiber in a matrix of Nylon, providing more rigidity than a standard nylon sole. It's 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 for walkability. The Sole uses 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. 
Material: 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.  
Techno-3 System: The 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 a proprietary SIDIWire material that is completely non-binding for intuitive and effortless on the-fly adjustments. Like most SIDI small parts, the TECNO-3 SYSTEM is replaceable.
