The exclusive and elegant design of the MTB Aertis takes off-road footwear to a whole new level. Combining premium microfibre suede construction with Firmor technology for extra wrap-around support, this shoe makes every journey easy. 

The revolutionary Firmor strap provides optimal support and helps relieve lateral pressure and speeds up the fit while closing evenly to prevent pressure points. 

Aertis is undoubtedly committed to reducing excess weight to help improve performance. The Aerolite carbon fibre injected nylon sole is completely new and provides maximum grip in all conditions and greater walking comfort. The toe cap is replaceable and always offers the possibility to attach crampons to improve traction on particularly treacherous terrain. 

The open cell mesh structure at the front is designed to allow the shoe to breathe. The new heel is contoured and comfortable, while the Soft Instep - made from a highly technical material that promotes airflow - is now integrated directly into the upper with its elegant matt finish.  

Inspired by the world of running, the tongue has a flat seam that does not overlap with other materials to avoid chafing and pain. 

Sidi Aertis is a shoe designed for those who want to make everyday adventures special, whether they are experts or curious off-road novices.
