1.1 Construction and Function

The 1S49, 1S66, 1S67 and 1S90 SACH (Solid Ankle Cushion Heel)
prosthetic feet are suitable for use in both modular prostheses and
exoskeletal prostheses. The functional properties are achieved
through the combination of a contoured core and functional foam.

1.2 Combination possibilities

This prosthetic component is compatible with Ottobock's system of
modular connectors. Functionality with components of other manufac­
turers that have compatible modular connectors has not been tested.
