In Eastern Europe, though I should say Central-Eastern as the Hungarians are tetchy about being classed purely as Eastern Europe, and Russia it is an old wives tale that if women get cold feet, it will then make them infertile.
I have had many experiences, during my time in Russia & Hungary of older women staring at me, pestering me, shouting at me or just pointing at me because of my shoes. In my dormitory in Russia my бабушка would tell me off for only wearing socks. I tried to explain to her that this was because in civilized countries, aka the US & UK, people have carpet in their houses so you don't get cold feet & I was fine! She wouldn't take no for an answer, often she would accompany me to my room just to watch me put on my shoes.
Here in Hungary I have had the same thing. Most of the time I do wear my UGGs or winter boots, but if I'm going out for a drink I wear my brogues. The women here just point, stare and whisper at them. My feet aren't cold and if they were, it's my problem not theirs. I just find it hilarious and I also quite enjoy irking them by looking like I have cold feet! They stare at me in my UGGs boots anyway, well at my Western or different looking clothing.
It's just a fact of life here in Eastern (CENTRAL EASTERN) Europe that if you're not from here, you're going to get stared at. They don't have the same social stigma when it comes to staring that we do. It's totally fine to stare a girl down on the tram. Interesting.
