Silicone liners

Liners are the secure connection between the user and the prosthetic leg. They ensure a pleasant wearing comfort and protect against pressure points. Silicone liners are the ideal solution for medium and high activity levels.

Varied selection

The right liner for every residual limb: Depending on the condition of the residual leg, different designs and many sizes are available. The silicone liners are available in two different wall thicknesses (3 and 6 mm) and optimally absorb shocks.

Depending on the activity and socket technique, prosthetic specialists can choose between soft and medium firm silicone liners, as well as with distal (locking) connection or without distal (cushion) connection. In the trans-femoral area, the Control4Sil sealing lip liner ensures a perfect hold thanks to the vacuum socket technology (VST).

Innovative knitting technique

The advantage of our silicone liners: the innovative circular knitting technique. This means that the prosthesis liners do not require any lateral seams and are much more durable and hard-wearing! The cover is easy to unroll and yet robust. A coloured orientation line assists patients with the daily donning.

The integrated matrix reduces longitudinal movement and has a stabilising effect. It is incorporated directly into the fabric so that it cannot detach from the gel.

Practical: Thanks to the coloured rotation caps at the end of the liners, the model can be recognised at first glance.

With anti-friction coating: The Control4Sil sealing lip liner is made of medical-grade silicone and connects the prosthesis and residual limb via four ring-shaped sealing lips (vacuum socket technology). This anti-friction coating facilitates the donning and doffing of a prosthetic leg.


Liners lie directly on the skin. The skin on the residual limb is often sensitive and tender. When manufacturing our products, we use high-quality materials and an antibacterial finish. This technology limits the recolonisation of bacteria and microorganisms.

The silicone used (medical grade silicone) is very soft on the residual limb and comfortable for patients to wear. An aloe vera additive nourishes the skin and retains moisture.
Cleaning the liners regularly is crucial for optimal hygiene. You will find suitable care products in our product range, such as the Skin Care Wash Lotion.

Convincing quality

Quality and service – for patients and technicians. Made in Germany, the prosthetic liners feature first-class product quality and comply with all requirements of the EU Medical Device Regulation (MDR).

Based on our many years of experience and expertise, we work to constantly improve our liners and provide reliable support for every concern. For holistic care in the area of socket comfort.
