Sidi MTB Aertis MEGA black/black 40

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.

MTB SR17 SOLE

The new Sidi MTB sole is lighter and more efficient and is made of nylon with PU inserts (polyurethane). 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 pedaling and flexion when walking.

TECNO-3 SYSTEM

The TECNO-3 SYSTEM adjusts the fit over the entire length of the shoe and the upper material to the shape of the foot for a customized fit. SIDI's famously reliable and interchangeable closures are enhanced by an all-new proprietary SIDI wire material that is completely non-binding and allows for intuitive and effortless adjustments on the fly.

FIXED CLOSURE SYSTEM

MEGA LEAF

The MEGA fit means that even those with a slightly wider foot can wear Sidi cycling shoes comfortably.

4 mm wider over the ball of the foot, more volume, a high instep and a wider heel cup. Mega lasts are EE or EEE width
