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
(Figure 4) .
Permanent Wedge Placement
• 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 5) .
Instant adhesive is necessary to bond the urethane heel wedge. The
adhesive cures in 15-20 seconds.

part. To secure its position a drop of instant adhesive can be used on one
side.
