Product Description The Runway® is a carbon fiber adjustable heel height prosthetic foot. Its anatomical gliding
ankle maintains appropriate foot alignment to provide knee stability and consistent
performance at all heel heights. The Runway® carbon fiber material stores and returns
energy so that users can walk farther, faster, longer. The Runway® fiber layers are tailored
to an individual’s body weight and impact level, providing a customized product for superior
comfort.
Bench Alignment Prior to donning the prosthesis:
• Plantarflex/Dorsiflexion foot to match the shoe heel height. (See Operation Section)
• Adduct/Abduct socket to provide appropriate frontal plane angle.
• Flex/Extend socket to provide appropriate sagittal plane angle.
• Move the socket to ensure the weight line falls along the anterior edge of the pylon (see
illustration).
Dynamic Alignment To optimize the heel to toe rollover motion, adjust the following variables:
• Anterior/posterior foot placement
• Dorsiflexion/plantarflexion
• Heel stiffness
Heel Stiffness Heel too soft
Symptoms
• Foot flat occurs too rapidly
• Toe feels excessively stiff
• Knee hyperextension
Solutions
• Shift socket anteriorly in relation to the foot
• Attach rubber
stiffening bumpers
Heel too hard
Symptoms
• Rapid knee flexion, instability
• Heel to toe progression too rapid
• Lack of energy return sensation
Solutions
• Shift socket posteriorly in relation to the foot
• Verify appropriate foot module category
Toe Stiffness
Toe too stiff
Symptoms
• Flat spot in rollover motion at slow cadences
Solutions
• Consider a lower category foot module
Toe too soft
Symptoms
• Clicking noise at
initial contact
• Excessive toe deflection with high impact activity
Solutions
• Consider a higher category foot module

Stiffening Bumpers Rubber
stiffening bumpers
are included to adjust the heel stiffness during
loading
response . The bumpers may be temporarily attached between the heel lever and the keel
using the pre-applied adhesive in the location indicated on the bumper package to increase
heel stiffness one category. If the heel stiffness is too stiff, move the bumper posteriorly;
too soft, move it anteriorly. For permanent placement, clean off the pre-applied adhesive
with Acetone, and adhere bumpers using Super Glue (cyanoacrylate).
Spectra™ Sock Replace Spectra™ socks at intervals appropriate to the user’s activity level to protect the
foot shell and minimize noise. Failure to inspect and replace the Spectra™ socks may
prematurely wear the foot module.
Foot Shell Use the Foot Shell Removal Tool (ACC-00-10300-00) to install or remove the foot shell to
prevent damage to the foot module.
There is a potential for interference between the button and foot shell. If this is the case,
the prosthetist will be required to grind the foot shell in those areas where interference is
causing the button to not seat fully.

Warranty: Foot module (36 months)
Ankle mechanism (18 months)
Foot shell (6 months)
Operation
(Prosthetist)
• Depress the adjustment button.
• To increase heel height, apply pressure simultaneously to the top of the toe and
the front of the knee, creating a plantar flexion moment at the ankle.
• To decrease heel height, press down on the toe and back of the knee to apply
a dorsiflexion moment at the ankle.
• Verify foot shell interference is not causing the button to not seat fully(high and low
settings).
• Verify the adjustment button has returned to its original position before allowing
ambulation.
• If the adjustment button sticks, free by applying alternating dorsiflexion/plantar flexion
moments to the ankle.
Operation
(User)
• Your prosthetist may let you use the prosthesis without a foot shell for a short period
of time, allowing you to visually learn to adjust the ankle mechanism by setting the
pylon in the correct vertical orientation after changing shoes.
• Inform your prosthetist if the toe and heel of the foot do not feel balanced.
• Be seated in a chair to adjust the heel height.
• Push the button in with your thumb to adjust heel height. Move the ankle to the desired
location by sliding the foot forward or backward with other hand. Do not attempt to
twist the foot.
• Ensure the locking pin is fully engaged by attempting to adjust the ankle without
pressing the adjustment button. This is to ensure the ankle will not slip into the next
lower adjustment.
• Avoid actions that would interfere with the heel adjustment mechanism (i.e., over-
tightening shoelaces or shoe straps)
• Active use may occasionally cause the adjustment button to stick slightly. Should this
occur, the button may be freed by pressing down alternately on the toe and heel for a
button stuck between positions. The button can also stick when in the closed position.
In this case, a gentle strike on the button should free it.
