The SIDI Zero Gore 2 is an excellent cold weather/winter road cycling shoe with a Gore-Tex inner liner. Stay dry, warm and comfortable. Enjoy your ride. One of the most exhilarating things in winter is enjoying the fresh crisp air while cycling without having to think about cold, drizzle or simply bad weather. SIDI has redesigned the line of winter season cycling shoes taking into account everything that is strictly essential during the cold season: warmth, protection, breathability and waterproof comfort.

Both the road and gravel/MTB winter versions have an upper made of mesh and MicroTech Microfiber that guarantees lightness and stability with the interior lined in Gore-Tex® to prevent water from entering. The Tecno 3 closure system is a durable and replaceable mechanism that adapts the shoe upper to the shape of the foot for an excellent personalized fit. 

The SIDI Zero Gore 2 is the road version, suitable for road cycling, characterized by the redesigned Carbon Millennium 5 sole, a composite carbon fiber/nylon sole. The fusion of these two elements makes it more durable by reducing any changes in the technical characteristics that normally occur with prolonged use and continuous change in temperatures. This version takes advantage of further stability guaranteed by the reinforced heel, which provides greater transfer power with a new ultra-light design. SIDI replacment parts available. Size range:  full sizes only

SIDI size measurement procedure.
Measure your foot by following these steps to obtain the reference measurement.
1.Put a piece of paper on the floor and mark the following points.
2.Mark the point in front of the tip of your longest toe and then mark the heel point for both left and right
3.Measure the distance between the heel mark and the toe mark. Record the cm/mm measurement and compare to the size guide chart for the suggested size. Use the size of the larger foot, most people will have slight difference between the left and right foot.

TECHNOLOGY
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. Millennium 5 Sole heel pad has a new design and it is very light.
MILLENIUM 5 SOLE: The redesigned MILLENNIUM 5 SOLE is constructed from injected carbon fiber in a nylon matrix. This increases sole stiffness and durability, ensuring optimum performance in the face of prolonged use and temperature changes.
