• At initial contact the amputee has poor control of his prosthesis.
• Minimal energy return feeling.
• Knee may become unstable.
Actions
• Replace heel wedge with a smaller one.
• Shift socket posterior (or foot anterior).
HEEL WEDGES (Figure 3)
A 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.
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
• Secure in position with tape wrapped around the foot module
Permanent Wedge Placement
• 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 4).
• Instant adhesive is necessary to bond the urethane heel wedge. The
adhesive cures in 15-20 seconds.
HEEL ASSEMBLY
If it is necessary to replace the heel component use Loctite 410 and
torque to following specifications:

HEEL DIVIDER
The heel divider should be placed in the last third of the splitted heel
part. To secure its position a drop of instant adhesive can be used on
one side.
PROTECTIVE FILM ON PYRAMID
The protective film protects the pyramid from scratching. Remove the
film when the fitting is complete.
DEBRIS BETWEEN BLADES
Noise could occur if sand or debris are present in between the upper and
lower blades, same could happen between heel plate and lower blade.
Use compressed air to remove debris in between the carbon parts.
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
