Loki wears the socks because he likes a little mischief and surprise under that all-black suit of his. He actually had “HULK – THE STRONGEST AVENGER” socks done especially for him, which disrupted his sex life for a week because Thor is still sensitive about that one.
Thor’s learning the Theremin for revenge purposes which is working amazingly. Or so he thinks. Loki has now completely mastered silencing charms.
“Loki wears the socks” sounds like some strange variant of “wearing the pants.”
