ALIGNMENT: (Figure 2)
The heel wedge
• Provides smooth roll over and improved cushioning at heel strike.
• The heel wedge is an essential component for
Flex-Foot
Assure function.
! the heel wedge should always be used with the foot.
BENCH ALIGNMENT
1. Fit the foot cover
(Figure 3 & 4)
.
2. Adjust to appropriate heel height (using the shoe).
3. Introduce appropriate socket angles.
4. The load line should fall through the 1/3
rd
mark on the brim of the foot
cover. The mark represents the junction of the posterior and the
middle third portion of the foot.
DYNAMIC ALIGNMENT
• The heel stores energy at heel strike and slowly releases it to assist
tibial progression.
• The forward momentum results in the toe being loaded for optimum
energy release at toe off.
• The heel wedge greatly influences Flex-Foot
Assure dynamic
functions.
Heel too hard
Symptoms
• Rapid heel to toe movement.
