If a 2 year old child is suspected of having a flexible flatfoot. It is important to rule out rigid flatfoot, that is, to rule out flatfoot caused by the tarsal coalition and the vertical talus, because if these two causes of flatfoot require surgical treatment, or a series of orthopedic treatments with a cast. Flexural clubfoot is actually asymptomatic and does not require treatment in children as in other older children. However, some children may have severe valgus, and sometimes it is recommended that the medial pads be elevated and rigid arch insoles be developed, which can improve the valgus pattern of the foot to some extent.
