Crush It Massage Ball to roll your sole. What part of your foot do you love massaged the most, besides the whole thing? Just place that spot on the ball, apply some pressure, and get to rubbing out all those tight crunchy bits with this textured massage ball. The nubs are soft enough to not poke the shit outta your foot but tough enough to provide a deep massage to get in-between the layers of muscle, fascia, and bone. The acupressure knobs on this ball will fit perfectly into those super tight, hard to reach areas.
