While AJR wrote their third studio album, the band created "Socks", finishing the song on July 24, 2018.
AJR decided to finish "Socks", re-writing the track's chorus with the new title "Adventure Is Out There" and making band member Ryan Met the song's lead vocalist.
[4] "Adventure Is Out There" is an upbeat folk-pop song,[5] primarily featuring a Southern-style guitar over the band's signature pop sound.
[6] The Globe described this composition as being driven by a "shuffling drum beat",[7] while Iowa State Daily compared it to the band's debut studio album, Living Room (2015).
[8] The track lyrically uses losing socks behind as a metaphor for freedom,[9] seeking an optimistic break in routine[10] with inspiration from the album's central theme of holding onto childhood.
