Arch support is typically recommended for both flat feet and high arches. In the case of flat feet, the arch of the foot collapses and can cause excessive pronation (inward rolling) of the foot during walking or running. This can lead to various foot problems such as plantar fasciitis, shin splints, and knee pain. Arch support helps to maintain proper alignment and prevent overpronation.
On the other hand, individuals with high arches often experience supination (outward rolling) of the foot, which can also lead to foot problems such as ankle sprains, stress fractures, and calluses. Arch support helps to distribute the weight evenly across the foot and reduce the pressure on specific areas of the foot.
Therefore, whether you have flat feet or high arches, wearing shoes with appropriate arch support can help improve your foot health and prevent related problems.
