Vertical talus is a congenital foot disorder, which means it is present in babies at birth. The foot turns outward, creating a rigid flat foot. To visualize it, think of the foot’s arch curving down and out like the bottom of a rocking chair.
Left untreated, a child with vertical talus begins walking on the inside of the foot. This leads to the formation of painful calluses, skin breakdown and foot pain. It affects a child’s gait and ability to wear properly fitting shoes.
