Underpronation. Underpronation is a term often used by runners, joggers and sports enthusiasts to describe the gait cycle when there is a lack of pronation. Pronation is the natural rolling motion of the foot as it moves from the heel to the toe, and it is important for shock absorption and proper weight distribution.nderpronation can be caused by structural abnormalities in the feet or when previous injuries to the feet have damaged the tendons and muscles, or when there is muscle imbalance or a particularly tight Achilles tendon.
Over-pronation means flattening of the arches and inward tilting of the ankles when your child is standing (when your child's feet are viewed from behind) Pronated foot structure is often inherited. Before children reach the age of 3 or 4, it is normal for their feet to appear flat because of a normal fat pad under the arch.
