Rocker bottom foot, also known as congenital vertical talus, is an anomaly of the foot.^[1] It is characterized by a prominent calcaneus (heel bone) and a convex rounded bottom to the foot.^[2] It gets its name from the foot's resemblance to the bottom of a rocking chair.

It can be associated with Edwards' syndrome (trisomy 18) as well as Trisomy 9 and mutation in the gene HOXD10.^[3] It can also be associated with Charcots foot.

Type II should be managed conservatively whereas type I and Ia requires to be treated surgically.^[4] Surgery involves four major steps:^[4]
