Instructions
The Aeris Performance 2 is designed to be maintenance free. The foot is
water resistant; however, if the foot is submerged in water, the foot and foot
shell should be rinsed with fresh water and dried immediately. The Aeris
Performance 2 should be inspected every 6 months for signs of abnormal
wear and that the attachment/alignment screws are secure.
Instructions to the Practitioner
• Please review the indications, contraindications, and FAQ sections of
the manual before use of the foot. These instructions should be read
prior to tting and followed to ensure the proper integration of the Aeris
Performance 2 into the patient’s prosthetic system.
• The foot stiness is based on weight and activity level. Please provide
accurate patient information so that the appropriate foot may be selected.

Installation
1.0 - Product Description
The Aeris Performance 2 foot uses two
carbon composite elements that conform
to terrain while storing and releasing
energy during gait. The foot is designed
to be used with most pyramid receiver
devices (Figure1). The pyramid dome for
the foot is permanently attached to the
pylon (main and top) spring and should not be removed.
2.0 Static (Bench) Alignment
Standard bench alignment techniques may be used for the Aeris
Performance 2 foot. Before aligning, the initial heel height should be
established. The foot is designed for a 3/8 in. or 1 cm heel height. The initial
heel height can be established with a simple spacer under the heel. The top
of the pyramid should be parallel with the work surface before proceeding
with alignment. A backward leaning pylon indicates that the heel height is too
low and will make late stance rollover dicult.

Transtibial Bench Alignment
The socket should be set in the proper
amount of inset found in the evaluation.
When using an integrated shuttle
lock/distal attachment component,
the plum line from the bisection of
the socket at the proximal brim in
the frontal and sagittal plane should
bisect the ankle pyramid. When using
separate suspension and attachment
components, the foot may be slightly
inset 1 – 12 mm depending on the limb
length. Short limb lengths are set with
very little inset of 2 – 3 mm and longer limb lengths may tolerate a greater
varus thrust at 10 – 12 mm. The longitudinal axis of the foot will be outset
approximately 5° by aligning the medial border of the foot with the line of
progression.
Transfemoral Bench Alignment
Standard TKA alignment can be utilized with the trochanter line bisecting
the distal ankle. The knee is set 3-6 mm posterior to the TKA line. A plum
line may also be used from the proximal sagittal socket bisection, falling 10
mm anterior to the knee axis (or through the knee axis for an SNS unit) and
the 10 – 15 mm posterior to the mid-foot. The knee and foot should both
be aligned with 5° of toe out and external rotation respectively. The socket
should also be set in the proper adduction angle of 7 – 12° and the exion
angle should be 5° more than the hip exion contracture if present.
2.1 - Dynamic Alignment
The foot is exible and conforms to uneven terrain. This characteristic
may mask forefoot loading anomalies during static alignment that may
then become more noticeable during dynamic alignment. Small alignment
changes will smooth the transition from heel to toe and optimize gait.
Patient feedback during this process is essential. Adjustments of the plantar
and dorsiexion angles will help the patient achieve a smooth transition
from heel to toe. The pylon should remain vertical in the frontal plane
throughoutgait.

• Check for smoothness of gait and ground contact throughout the stance
phase of gait.
• If the tibial progression is slowed from heel strike to midstance, or the heel
compression is too great, dorsiexion of foot may correct this problem.
• If the socket progresses rapidly forward from heel strike to midstance or
the heel seems too hard, plantarexion of the foot may solve this problem.
• If the foot progresses too quickly from midstance to toe loading, increased
plantarexion may solve this issue.
• If the foot hesitates from midstance to toe loading, dorsiexion may be
indicated.
• Check to make sure the pylon is vertical throughout gait. If there is a
medial lean, tighten the proximal medial screw; if there is a lateral lean,
tighten the proximal lateral screw.
Special Considerations
Due to the torsion compliance of the foot, it is very important to establish the
proper external rotation of the foot in relationship to the socket. If the foot
rotates too far internally or externally, it may feel less stable to the patient.
Making an external rotation adjustment during the dynamic alignment
should ne-tune the stability of the forefoot and improve the rollover
characteristics of the foot.

3.0 - Foot Shell Installation and Removal
The foot features a unique cosmetic foot shell that is exible and durable.
Use care in the installation and removal of the foot shell to maintain its
appearance and durability.
NOTE: Never use a sharp edged tool such as a screwdriver to install or remove the
footshell.
Installation
• Pull the Spectra sock
provided onto the foot from
toe to heel, pulling excess
material to the ankle so that
it does not bunch under the
heel or toe of thefoot.
• Insert the forefoot into the
foot shell as far as possible.
Set the heel on a supportive
surface with the toe up and
push the shell onto the foot until the toe is in position.
• Rotate the foot side to side to allow the foot shell to slide onto the heel
• Push the foot shell up onto the heel or, if necessary, insert a shoehorn
into the foot shell and allow the heel to slide down a shoehorn into the
heellock.
IMPORTANT: The heel of the lower foot plate must slide into the heel lock in the foot shell
for proper alignment and to secure the foot in the foot shell (Figure 4).
Removal
• Place the foot on the bench so that the heel is hanging over the edge of
thebench.
• Apply downward force to the top portion of the foot shell at the heel and
the heel plate should pop out of the heel lock, allowing removal of the foot
shell by hand.
• If the foot shell is too tight, a smooth edged shoe horn may be used to
disengage the heel lock.

Frequently Asked Questions
What can the practitioner do if the heel or toe is too soft or
toorm?
The heel and toe rollover resistance may be ne tuned during the dynamic
alignment (section 2.1) by plantarexing or dorsiexing theforefoot.
How long should the foot shell last?
The foot shell is designed to provide realistic appearance and maximum
performance of the Aeris Performance 2. The life of the foot shell will depend
on level of activity and degree to which it is protected from wear and damage
with socks and shoes.
Can the pyramid be removed so that the foot can be bolted
directly to the socket or other attachment?
No, the pyramid attachment should not be removed or altered in any way.
Doing so will void the warranty and could put the patient at risk of injury.
Daily Care for the Patient
• Patients should clean the prosthetic foot shell with a soft cloth and a soap
and water solution and should inspect the shell for the presence of sand
or other debris weekly. The foot shell may also be cleaned with rubbing
alcohol (70%). Do not use acetone. It will damage the foot shell.
• If the foot performance changes or if it makes noise, the patient should
immediately contact his or her practitioner.
