lateral compression forces are transferred to the residual limb thanks to this
flexibility. This results in stabilisation, improved comfort and more natural
adaptation to the ground.
Carbon and polymer spring elements permit perceptible plantar flexion at
heel strike, a natural rollover movement and high energy return.
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 Intended use
2.1 Indications for use
The product is to be used solely for lower limb prosthetic fittings.
2.2 Area of application
Our components perform optimally when paired with appropriate compon
ents based upon weight and mobility grades identifiable by our MOBIS clas
sification information and which have appropriate modular connectors.
The product is recommended for mobility grade 3 (unrestricted
outdoor walker) and mobility grade 4 (unrestricted outdoor walk
m°
kg
er with particularly high demands).
The table that follows shows the suitable spring stiffness of the prosthetic
foot, matching the patient's body weight and the size of the prosthetic foot.
