While being one of the most frequent parental complained deformities, flatfoot does not have a universally accepted description. The reasons of flexible flatfoot are still on debate, but they must be differentiated from rigid flatfoot which occurs secondary to other pathologies. These children are commonly brought up to a physician without any complaint. It should be kept in mind that the etiology may vary from general soft tissue laxities to intrinsic foot pathologies. Every flexible flatfoot does not require radiological examination or treatment if there is no complaint. Otherwise further investigation and conservative or surgical treatment may necessitate.
