The navicular and cuneiform bones are connected by dorsal and plantar ligaments.

The dorsal ligaments are three small bundles, one attached to each of the cuneiform bones.

The plantar ligaments have a similar arrangement to the dorsal, and are strengthened by slips from the tendon of the tibialis posterior.

Mere gliding movements are permitted between the navicular and cuneiform bones.
