The Foot Massage Roller by Nicole Miller is designed to help relieve plantar fasciitis, heel, and arch pain. It comes with a textured surface that helps to stimulate blood circulation and ease away tension. The Foot Massage Roller has a non-toxic, gel filling which allows it to heat when placed in hot water and cool when put in a freezer. The varying temperatures are perfect for combating stress, muscle pain, or to treat minor foot swelling.
