Flat feet occur when the arch of your foot (instep) is not as pronounced as it ought to be — this can happen for a number of reasons including injury, arthritis, obesity or just a natural quirk. Our range of Insoles for Flat Feet can help to combat some of the complications that can arise when you have flat feet by providing additional support to the arch while cushioning and stabilising the entire foot, resulting in less fatigue, as well as a reduction in knee, hip and ankle pain.
