Our Hot & Cold Foot Roller is ideal for relieving plantar fasciitis, pain from heel spurs or just tired, achy feet. The unique shape allows the roller to effectively fit into the arch and the raised surface dots provide a kneading effect for extra relief. The soothing stimulation immediately relaxes muscles and eases tension. And our hot/cold technology allows the roller to maintain temperature for up to 30 minutes of hot or cold therapy.
