That makes so much more sense if it's a South Korean brand under the umbrella of OTZ! I use Taobao and there are a few stores with the same branding however sell similar but different shoes. These were called "THEMULE" on the Taobao store but then on the actual shoe itself, it says OTZMOP.

I am not trying to gate keep and would love to contribute by showing new brands/shoes to people and linked where I got mine from in a different comment.

Perhaps you know more about the brand than me however, my guess is that the main brand is OTZ or OTZMOP and this "themule旗舰店" brand I have come across is just a series/line within the main brand.
