SOFT INSTEP CLOUSURE SYSTEM 3
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.

TECNO-3 SYSTEM
SIDI’s TECHNO-3 SYSTEM dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customized fit.
SIDI’s 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 TECNO-3 SYSTEM is serviceable and 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 4 CARBON SOLE
The MILLENNIUM 4 CARBON COMPOSITE Sole features injected carbon fiber in a matrix of Nylon, providing more rigidity than a standard nylon sole.

The MILLENNIUM 4 CARBON COMPOSITE Sole is also more durable, completely non water- absorbent and mechanically stable, meaning it’s less susceptible to changes in stiffness resulting from aging, prolonged usage, and changes in temperature or humidity.

The MILLENNIUM 4 CARBON COMPOSITE Sole uses a standard 3-hole drilling pattern for compatibility with the best pedal systems available, and includes a printed 10 mm lateral and fore/aft cleat alignment scale on the sole for easy cleat alignment and replacement.
