The ant “foot” consists of a tarsal claw with two toes and the several segments above that I suspect are simply… well…floppy. Basically, I’ve seen no evidence ants can wiggle their ankles at will, but rather they seem to adjust the floppiness, or tension of the lower leg. The claws, however, show signs of dexterity, ants can control how sticky the soft pad of their foot is, but also seem to be able to grip and release with their claws. (how exactly are the muscles arranged?)
