Cuneometatarsal interosseous ligaments

Looks like

Strong short fibres between the cuneiforms and the bases of the long foot bones; the inner one is the Lisfranc ligament.

What it does

Lock the midfoot to the forefoot; the Lisfranc ligament holds the second metatarsal in its keystone slot.

Keeping it well

Lisfranc injuries are easily missed: midfoot pain and sole bruising after a twist need weight-bearing X-rays or CT.
