Please bring with you or wear comfortable clothes that you can move in and a jumper (be prepared for different temperatures). You can change at the venue.
I prefer people to be without shoes because then they can be more responsive – and some venue we use may request that shoes are removed (and these are carpeted). Some of the venues aren’t carpeted and in colder weather, I don’t want you to have cold feet. So you might want to bring some extra socks to wear or very light shoes.
However, people have participated in all kinds of footwear. Very heavy footwear is going to limit your movement and make it hard for you to feel free, and high heeled shoes/boots will definitely make it very hard for you to participate fully.
