Whatever the journey may be, Aertis is here to make it easier and better. The comfort of a premium microfiber suede construction meets Firmor technology, which provides lateral support. The nylon sole with a replaceable rubber insert ensures maximum grip in any situation and enhances walking comfort.

MTB SR17 Sole

The new Sidi MTB sole is lighter and more efficient, made from nylon with PU inserts. The shape of the sole profile has been specifically designed for mountain biking, allowing for good grip, facilitating mud distribution, and ensuring proper stability. The central insert featuring the Sidi logo is slip-resistant and particularly practical and useful for less experienced users. The toe area, which is subjected to more stress while walking, can be replaced with screws and still offers the option to attach crampons to improve traction on particularly muddy surfaces. The SR17 represents the ultimate result in terms of stiffness while pedaling and flex while walking.

Tecno-3 System

The Tecno-3 system adjusts the fit along the entire length of the shoe and the upper material for a customized fit to the shape of the foot. Sidi's well-known reliable and replaceable closures are enhanced by a completely new, proprietary Sidi wire material that allows for intuitive and effortless adjustments in no time.
