Known for their quality, comfort and fit, Sidi shoes are loved by cyclists the world over. The ever popular Ergo has been refined to include a Twelve Carbon Composite sole and Techno-3 Closure System. Light and stiff, The Ergo 4 is suitable for racers and enthusiasts alike.
To maximise energy transfer, it's important to have a sole that's light and stiff. Sidi's Twelve Carbon Composite sole is made with carbon fibre, injected in a matrix of Nylon. The result is a sole that doesn't absorb water or lose rigidity in hot or humid weather.
The Ergo 4's upper is constructed from an Italian microfibre known as Microfibra TechPro. This high-tech material is stable, water repellent and durable, whilst remaining light and breathable. With no harmful chemicals, it is also an environmentally friendly material.
Sidi shoes are renowned for their comfort. A Soft Instep Closure System is a wide, anatomically curved strap and soft, thermo-formed EVA pad that distributes pressure evenly over the instep area. As it's adjustable from both sides, you can customise it to the shape of your foot.
As an improvement on the previous model, the Ergo 4 uses a Techno-3 Wire Closure System, allowing a custom fit along the entire length of the shoe. The buckle is extremely reliable but is serviceable and replaceable, if it is damaged. A high security Velcro strap makes the closure even more secure, to ensure a perfect fit.
To complete the customised fit, the Ergo 4 features an Adjustable Heel Retention Device, which enables you to tighten the top of the heel cup so that the foot doesn't slide out during steep climbs or sprints. An anatomically shaped, reinforced heel cup stablises and supports the heel and allows increased power transfer. The heel pads can be replaced when worn.
The Mega option provides a fit that's 4mm wider across the ball of the foot. The shoe has more volume, with a higher instep and wider heel cup.
