Hi, I believe that you have an equinus- your foot is a bit curved; this is partly due to your body trying to compensate for the shortening, it also helps counter the weakness of the muscles around the knee. Ankle has a bit of stiffness
I believe. I would advise the use of specialized footwear that allow for the contour of the ankle & foot, and also help increase the height. Exercises & physiotherapy
can surely help you make the ankle more supple and better.
