Flat feet are an extremely common condition that can begin in childhood or emerge in adults. The arch of a flat foot collapses when weight is placed on the foot. As a result, a large proportion of your sole (bottom surface of the foot) touches the floor when you stand.
In addition to the arch flattening out, the ankle of flat feet roll inwards. This is also known as overpronation. For most, having flat feet is not a serious problem, until when it causes pain or discomfort.
How orthotics can help flat foot
Orthotics provide support to the arch and prevent inward rotation of the ankle. By doing so, the orthotic insert is reducing the amount of tension on the muscles of the feet that are actively trying to pull the foot back into a neutral position. Without the insert, these muscles can fatigue quickly, leading to strain and exhaustion.
Furthermore, there are numerous ligaments, located at joints, that connect the bones of the foot together. In flat feet, every time your arch flattens out, these bones separate and the ligaments are stretched out.
Repetitive movements, such as walking, place persistent pressure on the ligaments, and, over time, they can become damaged and irritated. By supporting the arch, orthotics allow your ligaments to remain more relaxed so that they can avoid being overworked.
