Massage and balancing platforms

Massager

— this feature means that the projectile is supplemented with a special surface with a massage effect. Usually, such a surface has the form of characteristic spikes of rubber or other similar material; acting on active points (primarily on the feet), such spikes have various positive effects — tonic, relaxing, restorative, etc. In addition, the massage surface is often simply more pleasant for the user than the usual smooth one.
