TWELVE CARBON COMPOSITE SOLE
Twelve Carbon Composite Sole is made with two different materials blended together, nylon and carbon fibre. 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.
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.
SOFT INSTEP CLOSURE SYSTEM
The Soft Instep Closure System is a wide, anatomically curved strap combined with a soft, thermo-formed Eva pad that distributes pressure evenly over the instep area. The Soft Instep Closure System is adjustable from both sides, to perfectly center the Eva pad over a high or low instep. The system eliminates the need for the High Instep Extender. The Soft Instep Closure System is replaceable.
HIGH SECURITY VELCRO
High Security Velcro straps with integrated locking polymer teeth, that engage onto each other when the strap is closed. This feature makes the closure more secure and the strap becomes unmovable.
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.
