The shoes were created for a non-Valkyrie to enter Valhalla on the Bifrost. The Bifrost connects the different realms of the underworld; sometimes as a bridge, other times as a teleport. The wearer of the Helskór can collect souls to build a dark army that will end all life on Earth (Like Hell Pt.1).
The person who wears the Helskór is permitted to take home a soul from Valhalla that is claimed to her.
In La Fae Époque, Dyson and Flora Blooms stole the shoes from Prince Felipe III, and to hide them from sight Dyson put them on Flora's feet. But the shoes were not intended for her to wear and they immediately tightened on her feet, began to burn her, and made her persona change from a peaceful Leshii into a killer. When Flora was shot to death by Crater, Dyson took the shoes off her, gave one of them to Angel, a fellow Shapeshifter, for safekeeping, and hid the other in his boxing championship belt.
In Like Hell Pt.1, Bo climbed to the summit of a rock spire in the American Southwest and found the second Helskór shoe hidden inside an eagle's nest. Afterwards, when she put both of them on her feet, she was teleported to Valhalla in a super solar flare created by the Bifrost.
The shoes were made by Hades to keep Bo where he wanted her. They transformed into metal boots and restrained Bo until she released the Pyrippus within her, becoming Dark Bo and feeding off the entire Fae colony and humans in the city (Rise).
- In Norse paganism, helskór ("hel-shoes") were put on the dead so that they could go to Valhalla.
- Hel, in Norse mythology, is originally the name of the world of the dead; it later came to mean the goddess of death, Hel. She was one of the children of the trickster god Loki, and her kingdom was said to lie downward and northward. It was called Niflheim, or the World of Darkness, and appears to have been divided into several sections, one of which was Náströnd, the shore of corpses.
