7 Fitting Advice

Springs are supplied as matched sets i.e. the heel, toe and axial springs 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.
Axial Stiffness
The axial spring controls both compressive and torsional resilience. Typical vertical movement
should be between 5–10 mm for normal walking. Alternative stiffness springs are available if
required.
Condition
Heel too soft
Heel too hard
Please contact your supplier if it is not possible to achieve a smooth gait after following the advice above.

Sinking at heel strike
Difficulty climbing over the toe

drop-off )
