Where conventional mechanical prosthetic feet have always represented a compromise between flexibility and stability, electronically controlled ankle joints have until now enabled primarily slight, gradual adjustments to the user’s current gait behavior.

But the new Meridium is completely different, featuring an impressive range of advantages that offer the user a significantly more precise adjustment to the current situation. As a result, the user feels extremely safe and enjoys a more natural pattern of movement.

Incorporating intelligent, real-time control, the 4-axis design adjusts itself immediately to the user’s walking speed and ground conditions, whether on slopes, stairs or varying terrain.

Additionally, when using the convenient Cockpit app for Android or iOS, users can also easily adjust the Meridium via smartphone.
