I like Tai Chi Slippers (shoes) because they are comfortable and light. I bought them because my tai chi class is at a local park and my tai chi teacher recommended them. They are heavier and more durable than the slippers I use indoors. There was a recommendation to order a size or two bigger, but I ordered a half size up. The fit is perfect with a pair of light socks. I will buy another pair after washing them. I want to see how much they lose.
