Ouch! Hope you heal quickly. In one of my exercise classes, we sit in a chair and roll our feet from side to side to strengthen our ankles. At New Bedford, MAs Summerfest I crossed the cobblestone streets (stupid because there are safer slabs to walk on if I'd gone out of my way) and felt my ankle start to twist but stayed on my feet. I'll never know if that was the result of the exercises, but I'm grateful because my ankles have always been weak and easily injured.
