In Salt to the Sea by Ruta Sepetys, the Shoe Poet (Heinz) is described as a thin, tall man with hollow cheeks and a patchy beard. He wears a long coat with frayed cuffs and carries a sack of shoes over his shoulder. His face is weathered and worn, and his eyes have a deep sadness to them.
Ingrid, on the other hand, is described as a plump woman with rosy cheeks and curly hair. She wears a green hat with a feather and a yellow coat with large buttons. Her eyes are bright and curious, and she has a warm, friendly demeanor.
It's worth noting that both characters are refugees fleeing the chaos and violence of World War II, and their physical appearances reflect the toll that this traumatic experience has taken on them.
