Help me find these boots! (PLEASE)

I saw these boots in a charity shop and made the stupid mistake of not buying them immediately. When i returned… they were gone ???? that was a month ago and i’m STILL thinking about them.

They are Rieker boots, but I can’t seem to find the time period, surely from the past 10 years? Any ideas where i should look to find myself a pair? (I have checked vinted depop and ebay in the UK ????)

And if not these specific ones, something similar? I like the asymmetrical patchwork, and the Burgundy red + brown colours!

Any help would be so gratefully received <3
