I managed to finish the second heel! Maybe even more importantly, I also wove in all of the ends from the cuff. I like to try to weave in ends as I go because it is way less of a mental hurdle than having to do all of them at once. The ends from the heels will still have to wait a bit, though. I prefer to have a few rows of the foot done first to make sure everything is even and tidy with no holes.
