7 Fitting Advice

Spring sets are supplied as matched pairs i.e. the heel and toe spring are designed to work
together to give smooth progression for most users.
Heel Wedge
A heel wedge is supplied with the foot. Fitting the wedge will have the effect of stiffening the
heel spring. These can be taped in place for trial. For permanent fitting, wedges should be
adhered in place by application of Loctite 424 (926104) between the lower contacting surface of
the heel and the wedge.
Heel Stiffness
Progression throughout the stance phase should be smooth; heel function is key to this process:
• Too soft a heel or load line excessively posterior will result in sinking at heel strike and
difficulty in getting over the toe.
• Too hard a heel or load line excessively anterior will result in a rapid progression through
mid-stance or jarring at heel strike.
Heel too soft
Heel too hard
Toe/ Blade too soft
Please contact your supplier if it is not possible to achieve a smooth gait after following the
advice above.
