The Sidi Ergo 3 carbon shoe is the newest addition to the Sidi road cycling shoe range. This new model is offered with two technology that have never before been released onto the cycling shoe market.
Sidi Vent Carbon Sole
Sidi introduces a newly re-engineered and lighter racing sole for the Sidi Ergo 3 shoe. There is an added vent inserted at the very top of the sole, which when open, gives great ventilation. Air will flow though predisposed channesl until an exhaust located towards the middle of the shoe. This new technology invovled Sidi modifying the removable insole and footbed of the shoe, but the result is a giant leap forward for cyclists. The Air-Vent can be opened or closed as needed.
The Sidi Vent Carbon Sole has been developed to assist with blood circulation by further advancing the technology behind the power transfer ability inherent in the design of Sidi Cycling Shoes.
These soles are built to give light flex towards the nose of the cycling shoes whilst maintaining an excellent level of stiffness thoughout the shoe's body.
For walkability, the Vent Carbon Sole includes a replacable polyurethane heel pad. This new sole is also compatable with all of the best cycling road pedals on the market and to facilitate cleat replacement, the Vent Carbon Sole features a 10 mm horizontal and vertical cleat alignment scale moulded into the sole itself. Finished with the Look Memory Eylet.
Sidi Soft Instep Closure System
The wide, anatomical and padded strap has been reduced and coupled to soft, thermoformed material increasing comfort and performance. It distributes pressure evenly over the arch area, adjustable from both sides.
Sidi Tecno II System
The Tecno II buckle uses monofilament line and a fine tooth ratchet for smooth adjustment and even pressure distribution. This allows frontal micrometric closure and adapts the upper part of the shoe to the shape of the foot for a customised fit. The Tecno II system is now smaller and can be replaced more easily.
Sidi Adjustable Heel Retention Device
The Sidi Ergo 3 uses a new technology for the heel-cup system. The retention device reinforces the top of the heel-cup and improves fit by closing the back of the shoe more securely around the ankle. A couple of screws control how tight the top of the heel is, these can be adjusted so that the heel stays tight on any steep climb and every sprint.
The reinforced Sidi Heel keeps the foot in position and avoids the shoe being deformed by extreme performance or prolonged pressure.
