Flame Waker Boots

The Flame Waker Boots are a vanity accessory obtained by opening Obsidian Crates or Hellstone Crates, found by fishing in Lava. They cause the player’s feet to leave trails of fire while moving on blocks. They are entirely cosmetic and provide no functional benefit of their own.

Not to be confused with the, which allow you to walk on lava (and other liquids), and provide immunity to fire blocks and 7 seconds of immunity to lava.

Trivia

 * "Get cold feet" is a phrase that describes people not showing up to an event out of a sense of fear or anxiety despite being expected to be there, such as people not attending their own wedding or not going to a party due to anxiety despite saying they would attend.
 * A "waker" is one who wakens or rouses someone or something; this refers to this item's ability to rouse up flames behind the player, akin to a ship's wake. The word "waker" also appears visually similar to "walker", which was possibly intended as a pun.
