Recently I bought a pair of 'runners' that said they had non marking soles, but when I turned them over they had a fuzzy/flocked bottom. "Gee that's strange", I thought, "won't that just wear off when I walk on the street?"
Turns out the fuzzy sole has nothing to do with non-marking, it has more to do with taxes and duty - read this article here. Pretty sneeky isn't it??
Q: What kind of running shoes are made from banana skins? A: Slippers.
