Oops, I believe I misunderstood You were probably talking about the gap in Korean socks to separate the big toe from the others lol.
And I thought I've found another being with funny feet
No, I have normal feet, thank goodness. I was talking about the Korean socks being shaped like mittens - a section for the thumb or big toe and another section for the digits. My daughters sometimes cringe when they see me. I am so uncool! And don't really care! But I do dress nicely when I have to be in public.
