If you have pain in your knees and ankles that immobilizes you or stop you from jogging, consider looking at whether your feet is balanced normally.
Supination (under pronation) is when the weight is shifted outwards towards the outer edge of the feet, resulting in more wear on the outer edge of the sole.
Over pronation is when the weight is shifted inwards to the inner edge of the feet, resulting in more wear on the outer edge of the sole.
