Spiky massage balls are used to release tight, uncomfortable muscles and improve circulation. We have found them to be particularly useful in helping relaxation of neck and spinal tension, hands and feet. They have also provided good results when used on the soles of the feet prior to martial arts or running sessions.
The balls work well when used in pairs (eg. alongside the spine or under the pelvis) but are sold singly.
Available in two sizes 7cm or 9cm. They are resilient and effective when gentler pressure is needed
