I first did yoga in the late 90s. My wife-at-the-time told me about it and suggested we go together. I realized that I didn’t have appropriate shoes, so I made a point to go to the store and buy some white tennis shoes. I’m pretty sure I went through my first yoga class wearing those shoes. It’s hard to believe now but, on the other hand, I think it would be a pretty bad-ass way to deal with my feet slipping on the mat.
