Whereas flat feet commonly are flexible feet, high arched feet tend to be rather stiff feet which can lead to overload on the sole of the foot. When the ankle/hindfoot tilts outwards into a so-called varus position certain structures, especially tendons and joints on the outside of the foot are prone to be overstressed. As for other conditions, there is a multitude of reasons why a foot is high arched but neurological disorders, trauma and genetics are the more common reasons. Especially the neurological cavus feet might be at risk of progressing over the years, hence a thorough history, clinical assessment and the input of a neurologist will help to clarify the diagnosis and the treatment plan.
