The “politex” material consists of several superimposed layers with different physical-mechanical properties, the compacted PVC is then coupled to two fabrics (knitted fabric + felt) which is then film-dyed for long-lasting color retention. "Politex" offers strong resistance to tearing, tearing, stretching and fading. "Politex" is made in strict compliance with European regulations and is a totally "green" product.
Tecno 3 system:
SIDI's TECHNO 3 SYSTEM dials fit along the entire length of the shoe, adapting the upper to the shape of the foot for a personalized fit. SIDI's famously reliable and replaceable closures are enhanced 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.
The reinforced heel keeps the foot in an optimal position and prevents the shoe from being deformed by extreme performance or prolonged pressure.
For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad.
Millennium 4 Carbon Composite sole:
The MILLENNIUM 4 CARBON COMPOSITE SOLE features carbon fiber injected into a nylon matrix, which offers more stiffness than a standard nylon sole. The MILLENNIUM 4 CARBON COMPOSITE SOLE is also more durable, completely non-water absorbent and mechanically stable, meaning it is less susceptible to changes in stiffness resulting from ageing, extended use and changes in temperature or humidity. A non-slip insert and a replaceable polyurethane heel are incorporated into the MILLENNIUM 4 CARBON COMPOSITE SOLE, to ensure walkability. MILLENNIUM 4 CARBON COMPOSITE outsole uses a standard 3-hole drilling pattern for compatibility with the best pedal systems available and includes a 10mm molded lateral and fore/aft cleat alignment scale on the outsole and Memory Eyelet for easy cleat alignment and replacement.
