Something’s Wrong
Admit it. You also had a hard time determining which is the left and right side of your footwear while growing up. This is why you wish somebody made shoes that indicated which one is left and which one is right. Well, somebody did, but they didn’t do it in the right way.
The slipper with the left should be for the right foot and vice versa. The reason why on earth someone would want to make a complicated thing even more complicated is unknown. But what is sure is that you must not buy these slippers at all costs except if you love giving yourself some headaches.
