Final answer:
Pes cavus, or high arch, is a condition when the medial arch of the foot is exaggerated, which may affect walking biomechanics and lead to potential foot problems.
Step-by-step explanation:
When the medial arch is exaggerated, leading to a high arch in the foot, this condition is known as pes cavus or high arch. The medial longitudinal arch is one of the three arches of the foot which include the medial longitudinal arch, the lateral longitudinal arch, and the transverse arch.
An exaggerated medial longitudinal arch can result in excessive strain on the feet and may necessitate medical attention or special footwear to alleviate discomfort. The foot's arches play a crucial role in absorbing shock and aiding in weight distribution during activities such as walking or running. Ligaments and muscles support these arches, and when the medial arch is significantly higher than normal, it may affect the biomechanics of walking and lead to potential foot problems.
