I bought Onitsuka Tiger sneakers about 20 years ago, although I didn't know the brand name at the time. They were so comfortable that a year later I went back to the store where I bought them, put them on and asked the seller if they still sell them. He said no, acted like I was an idiot even when I asked him to, and wasn't interested in helping me track her down. It took me 20 years, since there was no brand on either the outside or the sole, to get the idea to look for a label on the inside…
