Questions & Answers about Hællinn brotnaði í gær, svo ég fór með skóna til skósmiðs í morgun.

- hællinn = the heel
Here hællinn is the subject of the sentence, so it is in the nominative singular.
brotna means to break, become broken in an intransitive sense. It describes something ending up broken without focusing on who did it.
So:
This is different from brjóta, which is transitive and means to break something.
