• Minimal energy return feeling.
• Knee may become unstable.
Actions
• Replace heel wedge with a smaller one.
• Shift socket posterior (or foot anterior).
Heel Wedges
The wedge can influence the heel to toe function. Start altering the heel
resistance to improve foot response by adding a heel wedge. The small,
medium and large wedges can be interchanged to customize the
stiffness
and achieve the desired functional characteristics. The wedges can
be trimmed using sharp scissors to customize stiffness.
Temporary Wedge Placement
• Cut the wedge to the width of the foot module.
• Roughen the upper and lower surface of the wedge with abrasive
paper.
• Place the wedge in the angle of heel and foot module with the curved
surface of wedge towards the foot module.
• Secure in position with tape wrapped around the foot module
(Figure 6).
Permanent Wedge Placement (Figure 7)
• Apply adhesive on the lower side of the wedge only (1).
• Locate in the foot/heel junction and position before adhesive sets.
• For split toe feet install the heel wedge then remove a thin slice in the
middle by cutting with a sharp knife through the split in the carbon
foot module (Figure 8).
Instant adhesive is necessary to bond the urethane heel wedge. The
adhesive cures in 15-20 seconds. For removal the adhesive may be
softened by soaking in acetone or cyanoacrylate adhesive remover.
Heel Assembly
If it is necessary to replace the heel the heel component use Loctite 410

Heel Divider
The heel divider should be placed in the last third of the splitted heel

side.
FLEX-FOOT SOCK
The toe end of the sock is divided by a thread and fits within the toe split.
Upon fitting the sock, hold the top of the toe thread and slide the sock
into the toe split. The thread of the sock should rest on top of foot
module and not underneath the toe split. The sock should be loose from
the heel area and secured proximally with the cable tie provided.
