1.1 Construction and Function
The 1C30 Trias prosthetic foot is suitable for walking on various surfaces
and at variable speeds.
The functional properties of the prosthetic foot are achieved through the car­
bon spring elements. The prosthetic foot permits perceptible plantar flexion
at heel strike and a natural rollover movement. Stored energy is released by
the spring elements.
1.2 Combination possibilities
This prosthetic component is compatible with Ottobock's system of modular
connectors. Functionality with components of other manufacturers that have
compatible modular connectors has not been tested.

2.2 Area of application

ents based upon weight and mobility grades identifiable by our MOBIS clas­
sification information and which have appropriate modular connectors.
