Foot posture refers to the alignment and position of the foot when standing, walking, or running. It is influenced by the structure of the foot, including the arches, and can affect overall body mechanics. Proper foot posture helps distribute weight evenly and can reduce the risk of injuries. Common types of foot posture include flat feet, high arches, and neutral alignment. Each type can impact how forces are absorbed during movement. Understanding foot posture is essential for selecting appropriate footwear and for addressing issues like plantar fasciitis or shin splints.
