Bogensocken mit Struktur
This pattern is in German.
“Arch shaped socks in a structural pattern” are a variation of the Bogensocken, which you should read thoroughly, too, because there are a few details good to know.
Note: The “Bogensocken” pattern is a German translation of the Arch-Shaped Socks pattern by Jen Showalter.
It’s not a beginners pattern, some knowledge about sock knitting is advised.
The pattern gives no specifications about yarn or needles - normal fingering weight yarn and appropriately sized needles should work for this.
