If you are always busy in your job by standing or walking maximum time then i think you must need this.I am a user of The Porcupine Massage Ball.It is very much helpful for me.I like to using this Porcupine massage ball.Because it is very easy to use.When i sit down for watching TV ,reading books and then just roll away. It relieves pain in my foot since I have low arcs and feels great doing this.The foot roller is great for sore feet as it is not so smooth as massage ball.The Foot Roller Massager activates pressure points releasing healing energy to regenerate the feet and benefit the whole body. It is really a great item you can use while you are doing other things. I am rolling away now When i type this.I buy it from amazon.com/gp/product/B0063MRFA2
