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.

CALIPER BUCKLE
– SIDIs TECHNO-3 PUSH dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customized fit. SIDIs famously reliable and replaceable closures are improved by an all new proprietary SIDI Wire material that is completely non-binding for intuitive and effortless on the fly adjustments. Like most SIDI small parts, the TECHNO-3 PUSH buckle is serviceable and replaceable. It can be adjusted while riding, thanks to an innovative button which can be pushed to lift the buckle and facilitate the adjustment.

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. Millennium 5 Sole heel pad has a new design and it is very light.
