Sidi Aertis

Whatever the journey, Aertis is here to make it easier and better. The comfort of a premium suede construction meets Fiirmor technology that provides lateral support. The nylon sole with replaceable rubber insole ensures maximum grip in any situation and increased walking comfort. The Sidi MTB sole is lighter and more efficient and is made of nylon with PU inserts. The shape of the sole profile has been specially developed for mountain bikes, providing good grip, facilitating mud dispersion and ensuring the right stability. The central insert with the Sidi logo has a non-slip effect and is particularly practical and useful for less experienced users. The toe area, which is particularly stressed when walking, can be replaced by screws and still offers the possibility of fitting crampons to improve traction on particularly muddy surfaces. SR17 represents the ultimate result in terms of stiffness when pedalling and flexion when walking.
