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

MTB SR17 Sole

The new Sidi MTB sole is lighter and more efficient, made from nylon with PU inserts. The design of the sole profile has been specifically developed for mountain biking, allowing for good grip, facilitating mud distribution, and providing the right stability. The central insert with the Sidi logo is slip-resistant and particularly practical and useful for less experienced users. The toe area, which is subjected to more wear, can be replaced with screws and still allows for the attachment of crampons to improve traction on especially 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. The well-known reliable and interchangeable closures from Sidi are enhanced by a completely new, proprietary Sidi wire material that is entirely non-binding and allows for intuitive and effortless adjustments in no time.
