Just a few days ago I was remembering a pair of these that I picked up back in the eighties for… a school play? I liked them so much that I wore them until they disintegrated.
We picked them up from a martial arts store (this was during the Karate Kid fad), and sure enough, a quick search for "kung fu shoes" on Amazon is all it took, $10. I'm going to grab a pair as soon as spring rolls around…
