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.
1. Know the Difference Between Pronation and Supination. Both pronation and supination are issues signified by the way your foot hits the ground as you are running or walking. But while pronation involves and inward roll of your foot and ankle, supination is the outward rolling of your foot and ankle. In a pronated foot, the inside part of your foot and the arch absorb most of your weight as you land. A supinated foot, on the other hand, means that the outer edge (pinky-toe side) bears the majority of your weight. Neither foot position is healthy for your feet or ankles, as both can cause serious pain and injuries.
