Local culture...

...is based on old learned habits. In Finland people don't wear shoes in their homes. Floors are covered with soft carpets , or more like Scandinavian rugs. Houses are well insulated, windows sealed with triple glass, thus making it comfortably warm and not drafty at all inside the houses. A strange combination of Turkish and Japanese cultures one could say.

And if you try to point out a Finn out of the crowd, then just look at the shoes. Finns don't take care of their shoes. I guess it has something to do with the weather, which is dusty and muddy half of the year. Finns probably sees it pointless to spend too much time on brushing and polishing their shoes.
