What to wear
No special clothes are required to enjoy tai chi, so choose something loose and baggy that will allow unrestricted movement. After all tai chi is reknowned in particular for being practiced in the park by people coming together in community of spirit and in synchronicity of motion.
Footwear should be basic, as you want your feet to feel freedom of movement, so gym pumps are ideal. Avoid any footwear with moulded innersoles as these will not allow you to feel a connection with the floor and you will not be able to feel when you squeeze your toes together. There are 26 bones and 13 muscles in the foot and tai chi trains these muscles back into balance and strength.
Your feet need to be active and as close to their natural movment as possible. Some people get on very nicely wearing their favourite bedroom slippers, after all these are specifically designed for relaxed comfort. In the summer months socks or barefoot are common.
And as a final assurance, no yoga mats are required, everything in tai chi is done standing up (or on the odd occasion sitting down).
