The relief function automatically lowers the forefoot to the floor when you are sitting, providing a comfortable, more natural foot position.
Thanks to the automatic heel height adjustment, the Meridium is suitable for various types of shoes. The inconvenience caused by frequent shoe changes is now a thing of the past. With the Meridium, you can quickly and easily adapt the heel height to your shoes, whatever the occasion.
It's more than a prosthetic foot. It’s a foundation.

Meridium – balanced stability
Uphill or downhill – thanks to the Meridium’s ability to adapt, you can manage inclined surfaces effortlessly from the very first step. Increased safety thanks to more ground clearance when walking uphill, comfortable when going downhill thanks to the adapted rollover and fast full-surface ground contact.
The Meridium adapts to the terrain with every step. From cobblestones, to grass, to forest paths – it offers a high level of stability on different types of terrain thanks to real-time adjustment and improved ground contact.
The Meridium prosthetic foot lets you place your entire foot on the step as you go down stairs. Instead of thinking about positioning your foot correctly, you can concentrate on your surroundings.
The Meridium intuitively identifies when you are no longer moving and require a secure, stable stance – even on slopes or uneven terrain.
When sitting, the Meridium prosthetic foot lowers itself to the floor, which achieves a more natural-looking foot position and can also help relieve your residual limb.
Whether you are barefoot or wearing flat soles or heels – thanks to automatic heel height adjustment, shoes can be changed quickly and easily with the Meridium prosthetic foot.
The Meridium adjusts itself automatically to diverse situations. You can easily adjust the Meridium via a smartphone using the convenient Cockpit app for iOS and Android devices. The app can be used to change the heel height, for example, or to select from a range of preset MyModes. The app also displays additional information such as the charge level of your mechatronic prosthetic foot.

Stride adjustment in real time
1) The resistance is adjusted when the foot touches the floor to achieve comfortable heel leverage that matches the user’s stride length.
2) Based on the individually adjusted resistance, the speed of plantar flexion immediately adapts to the gait situation with every step.
3) Thanks to the high degree of mobility and real-time adjustment during rollover, you benefit from prolonged, full-surface contact with the ground for the greatest possible stability and excellent traction.
4) The movable toe plate provides a large contact surface and ensures uniform pressure distribution in the forefoot area when rolling over the toes. The Meridium’s four axles give you a smoother, more natural gait pattern when rolling over the foot.
5) When your foot lifts from the floor, it remains in a rolled over position and thereby offers an enhanced level of safety as you walk.
