1) Bring the prosthesis to full extension.
2) Measure from the bottom edge of the
upper knee part to the top edge of the foot
connection plate.
3) Add approx. 15 mm to the measured
length and transfer this to the functional
shank.
INFORMATION: On the functional
shank, measure from the top to the bot­

Adaptation for fitting users with feet with a high structural height
For a fitting with a foot with a high structural height, the inner diameter on the lower side of the
functional shank has to be adapted accordingly.

Vertical Shock:
1) Enlarge the opening on the lower side of
the functional shank.
2) Sand the diameter in the foam to 60 mm.
3) Foam material (e.g. Pedilen) can be
applied in the ankle area of the 1C61 Triton
Vertical Shock (below the pyramid adapter
and functional ring) to ensure a better hold
of the functional shank in the ankle area.
