Can I use this ball on the soles of my feet, and how should I do it?

Yes, the soles of the feet are one of the typical use areas mentioned for this type of massage ball. To use it, place the ball on a firm floor, stand barefoot or in socks, and gently roll the arch of your foot over it. You can control the pressure by shifting more or less of your body weight onto that foot. Start with slow, short rolls back and forth, and if you find a particularly tender spot, you can pause and apply gentle, sustained pressure for 20-30 seconds before moving on. This can feel especially relieving after a day spent on your feet or wearing shoes, as it helps relax the plantar fascia and muscles. For safety and comfort, avoid rolling over the heel bone or toes directly, and always listen to your body—if any movement causes sharp pain, ease off.
