Slipper culture in Taiwan is great! They come in all varieties and colors and a fundamental part of the TaiKe look.
People wear them around the house after having taken off their shoes. People wear them outside the house when taking out the trash.
One annoying thing that has resulted, however, is a foot dragging phenomena. Lots of Taiwanese drag their feet, even in regular shoes. When you're walking down the sidewalk, listen for that dragging sound.
I guess it really is no use explaining that our parents didn't want us to drag our feet as it gives people around you the wrong signal. That is, the weight of the world is on your shoulders. Oh what a burden!
Come on Taiwan! Stand up straight, take big strides and be proud!
