Product Details

Sidi Ergo 4 Carbon Mega

- 4mm wider across the ball of the foot
- More volume, a high instep and a wider heel cup
- Mega lasts are EE/EEE width

- TWELVE CARBON COMPOSITE sole is made with two different materials blended together, nylon and carbon fiber. It is made out of injected carbon fiber in a matrix of nylon. The nylon used doesn’t absorb water and doesn’t lose rigidity in hot or humid weather or as it ages. The result is a significantly lighter and stiffer sole.

- 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 a proprietary SIDI Wire material that is completely non-binding for intuitive and effortless onthe-fly adjustments. Like most SIDI small parts, the TECNO-3 SYSTEM is serviceable and replaceable.

- 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.

- The ADJUSTABLE HEEL RETENTION DEVICE reinforces the top of the heel cup and improves the fit by closing the back of the shoe securely around the rider’s heel. The heel retention device tightens the top of the heel cup so that the heel doesn’t slide out during steep climbs or sprints. Each side of the heel can be adjusted independently, for a perfect fit. For a custom adjustment turn the screw towards the + sign to tighten the heel retention device and towards the – sign to open it. Light weight, easy to use, and replaceable.

- 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.

- 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. The reinforced heel keeps the foot in a optimal position and avoids the shoe being deformed by extreme performance or prolonged pressure.

- For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad.
