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.

Raintex is a soft and breathable multi-layered fabric perfectly wind and waterproof.

The micrometric closure called “CALIPER BUCKLE” is adjustable by lifting the central buckle. In order to completely open, lift together both side buckles, or push the center button to slightly loosen one tooth at the time. The system is also adjustable during a race.

The reinforced heel keeps the foot in a optimal position and avoids the shoe being deformed by extreme performance or prolonged pressure.

Lighter and more performing the new Sidi MTB sole is made of nylon with PU (polyurethane) inserts. The shape of the sole tread has been specifically designed for mountain bike, it allows a good grip, facilitates mud dispersion and provides the right stability. The central insert with the Sidi logo works as non-slip and it is  practical and useful especially to the less experienced users. The toe area that is more subject to wear, especially when walking, can be replaced by screws and still offers the possibility to mount crampons to improve traction on particularly muddy grounds. SR17 represents the ultimate result in terms of stiffness for pedaling and flexion for walking.
