Caliper Buckle The micrometric closure called “CALIPER BUCKLE” is adjustable by lifting the central buckle. In order to completely open, elevator 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 unmovable. 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. 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. Millenium 5 Sole The redesigned MILLENNIUM 5 SOLE is constructed from injected carbon fiber in a nylon matrix. This infusion of carbon fiber in the nylon increases sole stiffness and durability, ensuring optimum performance in the face of prolonged use and temperature changes.
To find which Sidi size you are, follow the instructions below:
If you have measured correctly, you will have an accurate foot length in millimeters. Repeating the steps a few times will allow you to be sure you have measured correctly.
The length in millimeters on the size chart refers to the size of the last used, so if your foot length falls between sizes, be sure to size up rather than down.
