- Ventilated politex upper
- Twelve Carbon Composite sole in carbon
- Sidi heel
- Replaceable heel
The “politex” material is made up of several overlapping layers with different physical mechanical properties, the compacted PVC is then coupled to two fabrics (knitted fabric + felt) which is then dyed with film for lasting color preservation. "Politex" offers strong resistance to tearing, tearing, stretching and discoloration. "Politex" is made in strict compliance with European regulations and is a totally "green" product.
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
Twelve Carbon Composite sole:
The Twelve carbon composite sole is made with two different materials mixed together, nylon and carbon fiber. Made of carbon fiber injected into a nylon matrix. The nylon used does not absorb water and does not lose stiffness in hot or humid climates or with aging. The result is a significantly lighter and stiffer sole.
