Boot out of Australia?

UGG

Think of a cozy sheepskin footwear brand that’s often associated with Down Under.

This clue plays on the double meaning of "boot." In Australia, "ugg" refers to a type of sheepskin boot, so the word "boot" hints at the answer. The phrase "out of Australia" suggests the answer is something distinctly Australian, reinforcing "ugg" as the right fit. The wordplay ties the footwear to its country of origin.
