Foam stiffening bumpers are included to adjust the heel stiffness during loading
response. The bumpers may be temporarily attached with tape between the heel lever
and keel. If the bumpers provide excessive heel stiffness, exclude or trim as appropriate.
For permanent placement, adhere bumpers using Barge or similar contact cement.
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, and will
void the warranty.
When removing or installing the foot shell, use the Foot Shell Removal Tool (ACC-00-
