The Infinite Socket™TT-S
is a human-inspired
transtibial socket
designed for daily
adjustments. It optimizes
knee flexion without
sacrificing performance or
aesthetics, providing new
levels of force transitions
that dynamically conform
with the patient’s every stride.
The Infinite socket™TT-S is
designed to accommodate
daily volume management.
The goal is to provide the user
an optimal starting point to be
able to go about their day using the
adjustments provided by the socket.

Patient having too
much pressure on
distal fibula
• Turn BOA®dial clockwise
• Make sure alignment is correct
• Move anterior guides to offload sensitive areas
• Heat remold to increase relief
• Add socks or padding as you would in a traditional socket
Patient having
fibular head pressure
• Turn BOA®dial clockwise
• Make sure alignment is correct
• Move anterior guides to offload sensitive areas
• Shift posterior pressure pad laterally

Aligning the
L-Bracket
The L-Bracket slides to
accommodate up to 26 mm.
It may be used for foot
clearance or alignment
needs.
To adjust:
1. Loosen 4 distal mount
screws.
2. Slide desired amount.
3. Tighten 4 distal screws
per torque specifications.

Textile Cover
The textile cover provides
a cosmetic finish to the
socket. It is to be removed
prior to any adjustments.
To adjust:
Remove the cover, using a
2.5 mm wrench, unscrew
from the proximal
attachment points and
slide away from the
socket.
14
Tip: Cover can be machine washed
on cold and left to air dry.

Pressure
Management Strap
The closure system
provides a tapered closure
system. Closure bias can
be controlled with the
pressure management
strap.
To adjust:
1. Release BOA®dial to
relieve tension in the
lace.
2. Release strap from
peninsula (proximal
screw) and pull to
adjust.
3. Place screw at desired
position.
15
Tip: It is recommended to allow
patient to walk on socket for two
weeks before trimming pressure
strap excess.

Pressure
Management Strap
When strap is moved to a
more lateral position, the
closure system provides a
proximal bias concentrated
at the level of the patellar.
16
Tip: It is recommended to allow the patient
to walk on the socket for two weeks before
trimming pressure strap excess.
Lateral Adjustments Medial Adjustments
When strap is moved to a
more medial position, the
closure system provides a
distal bias concentrated at the
level of medial tibial plateau.

Anterior Guides
The anterior guides’
position can be adjusted
for line of pull control or
to avoid sensitive areas.
To adjust:
1. Remove guides using
2.5 mm hex wrench.
2. Remove stickers
covering additional
hole locations.
3. Place guide in desired
location.
17
Tip: Anterior guide location change is
only available for limbs longer than 15
cm.
The two most proximal anterior guides
cannot be changed in location.

Anterior Guide
Angle
Guides should be
positioned in an
orientation that evenly
splits the angle of pull.
Be sure the lace is not
running over the screw.

Posterior Pad
The posterior pocket
houses a flexible posterior pad.
This pad is removable,
replaceable and
customizable to adjust
posterior pressure.
To adjust:
1. Access the pad by
removing the two most
proximal anterior guides.
2. Slide the anterior elastic up
and over the socket.
3. Turn the pocket all the way up
to expose the pad opening.
4. Remove pad and adjust as
