Rubber stiffening bumpers are included to adjust the heel stiffness during loading
response. The bumpers may be swapped out by carefully removing inserted bumper, and
reinserting bumper of choice. If the heel stiffness is too stiff, go to the next softer
bumper. If softest bumper is inserted and is still too soft, check foot A/P alignment.
A Spectra sock is provided to protect the foot shell and minimize noise. Spectra socks
must be replaced at intervals appropriate to the user’s activity level. Failure to inspect
and replace the Spectra socks may prematurely wear the foot module, or foot shell, and
may void the warranty.
When removing or installing the foot shell, use the Foot Shell Removal Tool (ST&G Foot
shell Removal Tool) to prevent damage to the foot module.

• Inspect the foot module every six months. If the user is more active, more frequent
inspection may be necessary. Service as necessary. Replace Spectra sock and/or foot
shell if worn to prevent damage to the Toe Flex components.
• Toe springs should be inspected at least every 4 months. If necessary, springs can be
serviced and installed in your office with the dowel guide tool and available replacement
joint pin, springs. These are available for purchase, and the process is relatively simple.
• The foot module may be cleaned and/or disinfected with soap and warm water
solution. Avoid harsh chemicals.
Failure to adhere to the guidelines of the Instructions for Use will void the warranty.
• Never use the foot module without a foot shell. Failure to comply may cause
premature wear, loss of function, and/or product failure.
• Never expose or submerge the Toe Flex foot to salt water, chlorinated water or water
in general. Failure to comply may cause premature wear, loss of function, and/or
product failure. In the event of splash or exposure, the Toe Flex has to be serviced by the
fitting clinician to be sure all mechanical aspects are not compromised by corrosion.
• Always use the foot module with a Spectra sock in foot shell, and sock on the outside
with a shoe. Failure to comply may cause premature wear, loss of function, and/or
product failure.
• Never allow aggregates such as sand to remain in the foot shell. Upon exposure to
aggregates, immediately disassemble foot module and rinse with water. The abrasive
properties of aggregates will quickly wear the Toe Flex composite components of the
foot module.
• ST&G foot modules are manufactured to fit industry standard pyramids and receivers.
It is the prosthetist’s responsibility to select and/or fabricate properly fitting attachment
components.
• Never attempt to loosen any bolts affixing the Toe Flex Foot system connectors or heel
modules.
• Discontinue use and consult your prosthetist if any part of the prosthesis starts to make
noise.
• Inform your prosthetist if you lose or gain a significant amount of weight.
• ST&G foot products are manufactured and tested for a particular weight and activity
impact level. Use by another user for whom it was not originally manufactured may
cause injury and shall void any written or implied warranty or liability.
