Overlay™ represents the next generation of volume adjustment technology and is equipped with an integrated pressure pump that uses air pressure to allow easy and efficient adjustment of the residual limb's fit inside the socket. The major distinction of Overlay™ lies in its unique technology, allowing the patient to self-regulate the volume based on advanced air cells that dynamically work to adapt to volume changes. The result is a comfortable fit without the constant need to change prosthetic socks. Additionally, it reduces the need to produce new prosthetic sockets for the patient. This is especially beneficial for recent amputees who often require a change in socket.
