I don't understand the use of "even" here. Does it simply mean "common"?
Context:
Put on athletic clothing. Wear a tight-fitting shirt and pants so it'll be easier to hula hoop and so the hoop won't get caught on any loose clothing.
Comfortable shoes will also make it easier for you to hula hoop. They don't have to be athletic shoes, and the choice of
even wearing shoes at all, is optional. It will neither influence nor harm your attempt to hula hoop.
Avoid wearing any bracelets or any dangling jewelry that can get caught in the hula hoop.
