Each step we take while walking places 1-1.5 times of our body weight onto our feet, while running subjects our feet to 4-6 time our body weight. Even slight anatomical aberrations such as high or low arches, increased or decreased mobility in the foot joints or insufficient activity in the muscles in the lower legs, may cause major problems for anyone who walks, jogs or runs regularly, as such aberrations can change the alignment and strain of almost all joints. Overpronation, resulting from there being too much mobility in the subtalar joint, is typical and can be a leading cause of problems. Such excess mobility in the midtarsal joint can also affect the foot, especially in the final position before completing the step (forefoot pronation).
Some of the more common problems include the following
