At the end of the day, my feet are tired and achy. I enlist the aid of a tennis ball. Here’s what to do: with your shoes off, stretch the tissues in your feet that’s causing the inflammation over a tennis ball. Just roll your sole over and over the ball while you relax and your tootsies will feel the relief in no time. If you’re really talented, you can do both feet at the same time with 2 tennis balls!
