I am also a size 39 or 40. I found a couple small stores in Wan Chai that carried these sizes. But the quality was not exactly what I was looking for.
I stepped into a store and asked for size 40 for a shoe that I liked. The lady there said with wide eyes "no, no...no 40". So I asked what was the largest size they had. Her response was "9". I realised the store had shoes in UK sizes. Obviously size 40 was a shock for her!
VegemiteKid where is SOGO? Please excuse my ignorance, but is this a store or a neighbourhood?
