At birth of a ‘full-term’ baby the average foot length is 7.6 centimetres (range 7.1 – 8.7 cm). Foot growth continues to be very rapid in the first 5 years of life; slower development continues until skeletal maturity of the feet, which occurs on average at 13 years in girls and 15 years in boys.
Unlike the flexible flat foot that is commonly encountered in young children, congenital vertical talus is characterized by presence of a very rigid foot deformity. The foot deformity in congenital vertical talus consists of various components, namely a prominent calcaneus caused by the ankle equines or plantar flexion, a convex and rounded sole of the foot caused by prominence of the head of ...

Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
Foot with a typical arch Flat feet of a child are usually expected to develop into high or proper arches, as shown by feet of the mother. Studies have shown flat feet are a common occurrence in children and adolescents. The human arch develops in infancy and early childhood as part of normal muscle, tendon, ligament and bone growth.

One biomechanical model estimated it carries as much as 14% of the total load of the foot. In an experiment using cadavers , it was found that failure of the plantar fascia averaged at loads of 1189 ± 244 newtons [ 3 ] (121 ± 24 kgf or 267 ± 55 lbf ).
The interphalangeal joints of the foot are the joints between the phalanx bones of the toes in the feet. Since the great toe only has two phalanx bones ( proximal and distal phalanges), it only has one interphalangeal joint, which is often abbreviated as the " IP joint ".
