Answer:
Bones of the Middle Foot
Humans have five metatarsals in each foot. The bones in your toes are called phalanges. The bones at the back of the foot, those lumpy things under your heel, are called tarsals. The bones in between are called the metatarsals. If you have occasion to look at a skeleton, they're the ones with more than passing resemblance to chicken drumstick bones.
The proximal end of each metatarsal, also known as the base, is articulated with the tarsal bones. The distal end of each metatarsal, also known as the head, is articulated with a phalanx (the singular of phalanges). Here, as elsewhere in the body, proximal means 'towards the centre of the body' and distal means 'towards the edge of the body'. Incidentally, the big toe is short-changed, having only two phalanges while the rest of the toes have three each.
Soldiers, sportsmen and ballet dancers are prone to fractures of the metatarsals, in these cases presumably related to spending too much time on one's feet.
