A human foot is an extraordinary complex that gets the least amount of well deserved attention. It is probably the most overused and the least glorified part of a human body. Bad shoes, poor posture, faulty body mechanics and simple overuse can all cause foot pain and tightness in the rest of the body.
One of the amazing benefits of giving your feet a little self-massage is gaining flexibility in your hamstrings and even releasing some lower back tension. When you massage the soles of your feet, you loosen the starting point of a network of connective tissue that runs all the way up your back body to the crown of your head. Tom Myers, author of Anatomy Trains: Myofascial Meridians for Manual and Movement Therapists (aff) has posted a fascinating video from a human dissection showing the entire Superficial Back Line of fascia, connecting from the feet to just above the eyebrows.
Whether you want to loosen your hamstrings, ease foot soreness or give your feet a nice massage after a long day spend 5 minutes every day rolling your feet on spiky or smooth sFera Balls. You will notice the difference immediately.
