Thanks again for the reply Karen, it's really appreciated.
To be honest there doesn't appear to be any difference between the two arches of my feet. When i sit and push my feet together there isn't any pain - out of interest, where should the pain be coming from?
The pain on my inside shin bone (above the ankle) and when pointing my toes subsides after a few day of no exercise. I only always feel pain when i rotate my foot or tap the inside ankle bone - the front of this bone rather than back (back meaning nearer the achillies tendon).
The orthotics were an off the shelf model, but made of hard plastic rather than soft. They were a 3/4 length model and have 2 wedges inserted into the sole to slightly tip my foot outwards.
Your advice is really helping Karen so if you require any further info from me please ask.
Many thanks
