These are the cooling gel slippers that help relieve common side effects of chemotherapy such as neuropathy pain, tingling, discomfort, and nail loss. The slippers are lined with individual gel ice cubes that are surrounded by a fluid-like gel and activated by cooling in the refrigerator or freezer. This unique cooling system slows temperature exchange and results in longer lasting cold treatments. Unlike similar products, more cooling gel is positioned directly over the toes, resulting in a longer-lasting cold therapy treatment in the area that needs it most. Made with stretchy side seams for comfortable wear and a soft inner lining that’s gentle against sensitive skin. For cold use only; not for use with pacemaker or insulin pump. Blue. Small/Medium (fits women's shoe sizes 4-9, men's shoe sizes 6 to 8 1/2).
