9 Fitting Advice
Elite blade springs are supplied as matched sets i.e. the blade/toe and heel 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.
