TWELVE CARBON COMPOSITE SOLE - TWELVE CARBON COMPOSITE sole is made with two different materials blended together, nylon and carbon fiber. It is made out of injected Carbon Fiber in a matrix of Nylon. The Nylon used doesn’t absorb water and doesn’t lose rigidity in hot or humid weather or as it ages. The result is a significantly lighter and stiffer sole.
SIDI HEEL CUP - Reinforced cup that stabilizes and supports the heel. Anatomically shaped plastic, reduces heel slip and provides increased power transfer. Provides additional foot protection in the event of a crash.
REPLACEABLE HEEL PAD - For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad.
VENTED POLITEX UPPER - 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.
These are a typical awesome Sidi shoe with a comfortable slipper-like upper and a stiff sole for good power transfer to the pedals. The price was right for these as well
