Where can I find the UGG clic bomber boots in a mens size 8?

HELP ASAP!!!! My boyfriends gonna be 15 next weekend and i want to buy him the UGG clic short mens bomber boots but the official UGg website is sold out of his size (mens size 8) in both the chocolate bomber and chestnut bomber boots. They have the mens size 9 but thats his normal size and his UGgs are an 8 mens because i checked the tag inside of his boots. Any ideas???? These boots must be really popular with boys/men because they are selling out fast.
