BENCH ALIGNMENT (Figure 2+3)
• Fit foot with selected cover.
• Adjust to appropriate heel height (using the shoe).
• Introduce appropriate socket angles flexion/extension and abduction/
adduction.
• Divide the foot cover into 3 equal portions.
• The load line should fall at the junction of the posterior and the
middle third portions as shown in the diagram (the mark on the brim
of the foot cover matches the one third portion).

DYNAMIC ALIGNMENT

The heel stores energy after initial contact, slowly releasing it at
midstance. The forward momentum generated by this action results in
the toe being loaded for optimum energy release at terminal stance.
The heel to toe action can be influenced by
• A-P positioning of foot
• Dorsi-Plantarflexion
• Heel Stiffness
CATEGORY SELECTION CHART
Please refer to the selection charts below to determine the appropriate
