One, on the eastern side, still stands about 0.81 metres high against the base of a boundary fence. The other, to the west, has sunk entirely into the ground. What makes them unusual is not their size or placement but what local tradition says they preserve: the imprint of a cow's hoof in one, and a thief's foot in the other.

The legend, recorded by Cuppage in 1986, describes a thief who attempted to steal a cow and was stopped by a holy man, whose intervention caused the thief's foot to become fixed in one stone and the cow's hoof to become embedded in the other. The story is a recognisable type in Irish hagiographic tradition, where saints and holy figures exercise power over movement, binding wrongdoers or animals in place as a demonstration of divine authority. What Cuppage could not resolve was any firmer connection between the two stones and the nearby ecclesiastical site. Their original function remains unknown, and the relationship between the stones and the religious settlement, if there ever was one, is unestablished. The name Cill Maoilchéadair refers to a church site, "cill" being the Irish term for an early ecclesiastical enclosure or church, and the landscape around it carries the usual layering of early Christian remains alongside older, less legible features.

The eastern stone is the only one still visible, modest in height and easy to overlook against the fence line. The western stone, now buried, leaves the pairing incomplete. Two stones, one legend, and a question about purpose that has never been answered.
