1 of 5 X 3 mm layer (1.5cm TOTAL - anything more will push your heel out of your shoe) heel raise easy peel-able layers means the orthotic can easily be adjusted to necessary height
For achilles tendon the height can be reduced as the injury gets better, for leg shortening / hip injuries adjust the raise to height required immediately
One will be required to treat leg length discrepancies, and 2 for achillies tendon injuries
The adhesive used is strong - this prevents the layers coming apart when not required to do so. We recommend applying a little heat with a hairdryer / on a warm radiator to make the adhesive more pliable when you wish to peel away layers.
