My feet are size 42. For most of my grown up life I wore 41 and it wasn't exactly comfy. I still sometimes get something in size 41 (Yes, I'm talking about those Beverly Feldman shoes from fleabay, but BF fits okay and one pair were thongs.) The Marc Jacobs ballet flats were cheap and 41. I decided they would work. They worked although it cost quite some effort to stretch them - and they are rather narrow than short as such.
When summer came, I started wearing thongs and sandals. Now I'm in Prague, I need to go to some discussion panel at the Ministry of Education so I took decent shoes with me. Said Marc Jacobs. On the first day, I decided that less than comfy is not a problem, I won't do any major walking etc. Today afternoon, I was highly inclined to go buy shoes NAO but it's rainy and I'm wintery-depressed and I had a problem with dragging my tired body to the metro station to go home.
During the Pilates class, my feet grew a few more blisters so I plastered and band-aided them and stumbled home, thinking that there's a shopping hell on the way so I'll act spoiled and go shoe-shopping at 9 pm. Shopping hell was open but the boutiques were closed. I fail to see a point of open mall with closed shops but I'm not your typical consumer.
The report on getting size 42 shoes in a country when normal range ends at 41 and the existence of abnormal is denied will follow.
