80s do seem to be a little bigger, but I think it's mainly the width of them. I usually wear a UK 11 and tried some 80s half a size smaller in a shop (mainly because they didn't have my size...LOL...) and at first I thought they were good, but after walking around for a couple of mins in the shop I started to think they were too small in length.
Ended up buying some UK 11s online
