Arch support refers to the design feature in footwear that helps maintain the natural shape of the foot's arch. This support can prevent discomfort and pain by distributing weight evenly across the foot. Proper arch support is especially important for people with flat feet or high arches, as it can help improve balance and reduce the risk of injury during activities like walking or running. Many types of shoes, including sneakers, sandals, and orthopedic shoes, offer varying levels of arch support. Additionally, orthotic insoles can be added to regular shoes for customized support. Choosing the right arch support can enhance comfort and promote overall foot health.
