What do you think of the foot shape?

If you can almost see the whole footprint, then your arch is very flat, which means you are likely to over-pronate. That is to say, at the moment when your foot touches the bottom, your arch collapses inward too much, and walking in an outward figure of eight will cause excessive movement of your foot and increase the probability of injury. Wear a special insole with balanced support when going out.
