Untied

The shoelace came untied.

My shoelaces came untied as I was walking down the street.

Your shoes are untied.

Tom untied the ribbon.

Tom's shoelaces are untied.

Tom untied the ropes.

His shoes are often untied.

Tom held the knife between his teeth as he untied the knot.

Tom didn't notice that his shoes were untied.

Wait a second. My shoe is untied.

The sack had been left untied, and so by wriggling a bit he was able to get his head through the opening and look out.
