7 Fitting Advice

Spring sets are supplied as matched pairs i.e. the heel and toe spring are designed to work
together. Progression throughout the stance phase should be smooth; the combined heel and
ankle function is key to this process.
If a smooth progression is not achieved, the following should be considered:
Ankle
too soft
Heel spring
too soft
Heel spring
too hard
Please contact your supplier if it is not possible to achieve a smooth gait after following the advice above.

Symptoms

Medium
Fit plantar flexion buffer.
A choice of medium and firm buffer
is available (the medium version is
castellated), see figs 1 & 2 below.
For trial purposes the buffer does not
need to be bonded. Final selection
should be bonded in position using
Loctite 424.
