Actions
• Replace heel wedge with a smaller one.
• Shift socket posterior (or foot anterior).
HEEL WEDGES
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 (Figure 5)
• 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 (Figure 6)
• Apply adhesive on the lower side of the wedge only.
• 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.
Instant adhesive is necessary to bond the urethane heel wedge. The
adhesive cures in 15-20 seconds.
PROTECTIVE FILM ON PYRAMID
The protective film protects the pyramid from scratching. Remove the
film when the fitting is complete.
FOOT COVERS AND SPECTRA SOCKS (Figure 3)
The foot is designed to be used with foot covers and spectra socks. When
installing and removing the foot covers use shoehorn to avoid damage to
the foot or the foot cover.
Please view the instructions for use for the foot covers before fitting them
and ensure that the user knows how to use them.
It is important that the middle section of the spectra sock covers the
topblade to make sure it doesn´t intervene with the movement of
the blades.
The thread of the sock should rest on top of foot module and not
underneath the toe split (Figure 7).
Use a shoehorn to avoid damaging to the foot or the foot cover.
1. Installing – Make sure that the foot module is placed completely into
the foot cover.
