Due North Foot Rubz Massage Ball
A small, firm, nubbly ball for rolling under the foot or in the palm, and one of the best-known in its category.
About the size of a golf ball and covered in small raised nubs. Roll it under the arch while sitting, or between your palms, pressing only as much as feels good.
Its size makes it easy to carry, and it is a simple, low-cost way to start giving your own feet and hands some attention.
