Soft Instep 2 - The anatomical and comfortable strap, placed on the top of the foot and coupled with a soft and thermo-formed material, will increase comfort and performance. It distributes pressure evenly over the arch area, adjustable from both sides to achieve the perfect center position. The system eliminates the need for the High Instep Extender. The Soft Instep Closure System is serviceable and replaceable
Caliper buckle - 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.
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 unmoveable.
Rubber toe - Upper part of the toe section is rubberised to resist and deflect impacts from stones or debris when cycling. It is made with anti-slip rubber
Sidi heel cup - The reinforced heel keeps the foot in a optimal position and avoids the shoe being deformed by extreme performance or prolonged pressure.
Sole Replacement System SRS - The SRS sole is replaceable. Its four tread panels, at the toe, both sides of the forefoot, and at the heel, are equipped with inox screws for easy removal and replacement. The PU material used for the SRS inserts has the right density for variable trial terrain. The tread panels and screws are available as spare parts.

Rated 5 out of 5 by Markypoo Brilliant shoe
Got these shoes in black, just bought a white pair. Most comfortable shoe I have ever had and thats not just cycling shoes, more comfortable than my trainers. Fantastic shoe. Seems expensive but well worth it.
