Our Treadmills

The innovation of SPRINTEX slat-belt technology

The Callis treadmills are based on a unique slat-belt running surface, the s²ap®. Slat belts’ advantage over traditional conveyor-type treadmill belts lies in their ability to absorb the impact when the foot hits the belt, providing a much more comfortable and natural gait training.

Callis slat-belts sit on 114 ball bearings that enable a fully frictionless movement of the running surface. Eliminating friction between the running surface and the frame ensures durability and a reduced maintenance time. Not to mention the significantly smaller energy consumption.
