In Norse mythology, a valkyrie is one of a host of female figures who choose those who may die in battle and those who may live. Selecting among half of those who die in battle the valkyries bring their chosen to Valhalla, ruled over by the god Odin.
Valkyries sometimes appear as lovers of heroes and other mortals, they are sometimes described as the daughters of royalty, sometimes accompanied by ravens and sometimes connected to swans or horses.
The name came after the design. I was designing a hygge boot sock for myself to wear as house socks. When the design was finished, I thought, this is something a female warrior would wear.

This sock can be knitted in 4 different lengths; Knee high, trouser, crew and mini crew just by adding pattern repeats to the leg.
4 rounds of the pattern repeat is knitted with smaller needles to create a 3D effect on the leg.
This pattern is worked in the round from the top down.

For a more hugging foot, the smaller needle may be used.
