Gel liners

Liners are the secure connection between the user and the prosthetic leg. They ensure a pleasant wearing comfort and protect against pressure points. Gel liners are the ideal solution for low to medium 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 gel liners are available in three wall thicknesses (3, 6 and 9 mm) and thus protect the pressure-sensitive shinbone area with additional cushioning.

Prosthetic specialists can also choose between a variant with a distal (locking) connection or without a distal (cushion) connection as well as an optional matrix.

Innovative knitting technique

The advantage of our gel 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: All gel liners are suitable for short-term use in salt and chlorinated water.
Good to know: The ContexGel liners are mouldable at 60 °C and can thus be optimally adapted to unusual residual limb shapes!


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 polymer gels used are very soft and comfortable for patients to wear. White mineral oils nourish the skin and retain 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.

Size determination: Measure the distal circumference approx. 4 cm and 30 cm (proximal) above the stump end and select the liner size in the area of the distal and proximal stump circumference according to the chart. Please note that transtibial stumps with ContexGel-Liners without distal connection require a ContexGel Knee Sleeve.
