The ball of my left foot hurts, from swing dancing. I've been doing a 2 or 3 times a week. I'm a lead, follows might find it's with their right. A couple months back I changed my style to be less flat footed, so now I'm dancing more on my balls, especially with the triple steps. This greatly improved my dancing, as i became more fluid, I used to find sometimes my feet felt like lead, and wouldn't always move fast enough. But now I think I'm paying the price. So exactly what part of one's feet is one meant to dance on?
