Here’s an update:
It just didn’t sit well with me that I was having to wait on my boots even longer. I sent them an email and they are sending me a refund. I offered for them to send me a pair without the zipper or just let me order a different style altogether, and they chose to refund the money.

This is disappointing in a way, because I really liked the boots. I’m glad they stand behind the product at least. Hopefully they can get straightened out soon.
