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.
