Socks and liners

Socks and liners provide an interface between residual limb and prosthesis. They protect skin and ensure comfort.

A prosthetic sock is designed to be worn under a suspension liner next to the skin. It relieves skin shear irritations and improves comfort with liners. Tested and proven beneficial for amputees who wear liners as the primary interface. Advanced materials improve liner's suction grip on skin. Quality socks are made of fibers that inhibit odor in the sock, transport heat and moisture away from the limb. They keep liner cleaner and helps control skin irritations. Our team will recommend post op, fitting socks, shrinkers, and every day socks suitable for each patient.


Liners play an important role in the comfort and health for prosthetic leg users. They fit over your residual limb and go between your limb and the socket (the socket is the shell that encases your limb and connects you to your prosthesis). Worn over your residual limb, it reduces movement and chafing between the skin and the socket. Liners are designed with specific characteristics to work with different suspension systems. Liners may have antibacterial additives, textile outer layers for easier application, anatomical shaping, non-stick treatments, variable thicknesses to accommodate sensitive skin, pre-flexed knees, as well as tough tear- and puncture-resistant formulas.


Silicone liners provides high stability and good adhesion if your limb has a lot of soft-tissue. It performs best with shuttle-lock suspension. Soft but resistant to pressure, silicone is durable and easy to clean. Silicone liners are recommended for individuals with a low to moderate activity level.


Polyurethane is great for even distribution of pressure in your socket. This type of liner offers a precise, intimate and comfortable fit and is a good choice for sensitive, bony or scarred residual limbs. Polyurethane performs best with vacuum suspension or suction suspension. Polyurethane liner is suitable for individuals from low to especially high activity levels.


Copolymer is soft, cushiony and highly elastic, offering good protection for low activity for many types of residual limbs. Usually a thermoplastic elastomer, which contains skin-friendly white oil, it is especially good for residual limbs with dry skin. Copolymer liners are suitable for individuals with a low activity level.

Sealing sleeves

Sealing sleeves are needed for vacuum and suction suspension. They create a seal around the socket’s top edge. After donning a liner (which acts as a second skin) and a prosthetic sock, you insert your residual limb into the socket. The liner extends beyond the sock, so rolling up the sleeve attached to the outside of the socket creates an airtight seal where the sleeve and liner overlap.
