Comfortable And Secure Confidence For Hard Pedaling

Whatever the journey, the Sidi Men's Aertis is there to make it easier and better. The comfort of a premium suede construction meets the Firmor technology that offers great lateral support. The nylon sole with replaceable rubber insert allows for maximum grip in any situation and increased walking comfort.

The Tecno-3 Push Flex completely eliminates the pressure zone on the instep and significantly improves the feeling of closure. Equipped with a smaller support surface on the tongue of the shoe with a central flexing system, it manages to fit a wide variety of cyclists, without creating areas of hyper pressure. It guarantees micrometric precision fit with easy to use instant release.

Designed for maximum lateral support, Firmor Closure contours the foot with a solid hold, and allow infinite size adjustment for an individual fit.

The new Sidi MTB SR17 Sole is made of nylon with PU (polyurethane) inserts and allows a good grip, facilitates mud dispersion and provides good stability. The MTB SR17 Sole represents the ultimate balance of stiffness for pedaling efficiency and flexibility for walking comfort. The central insert marked with the Sidi logo acts as a non-slip element. The toe insert is user replaceable, and offers the possibility of mounting spikes to improve traction on particularly muddy courses.
