Help a girl out who just wants some size 6 (uk) boots?

No 6 in the UK but seemingly in the EU sizing if you convert it
Am a couple of glasses of wine in so possibly being dim here!

I think they've translated the 39 to a 5 1/2 rather than a 6

Yeah I agree with the PP. I had this recently with some birk slippers and went for the 39. All good
