High arches, also known as pes cavus, refer to a foot structure where the arch is raised higher than normal. This condition can lead to an uneven distribution of weight across the foot, which may cause discomfort or pain during activities like walking or running. People with high arches often experience issues such as plantar fasciitis or metatarsalgia, as the foot may not absorb shock effectively. Proper footwear and orthotic inserts can help provide support and alleviate discomfort associated with high arches.
