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.
Pronation is a normal part of walking or running. When the outside edge of your heel hits the ground, it supinatesâor locksâto deal with the shockwave. Your foot then rolls in a bit and your heel moves outward. Together, these actions cause you to pronateâor unlock. Pronation helps you absorb shock and adapt to uneven surfaces.
