I ordered a waterproof cast cover called Xerosox from a company called ACTIVE FOREVER I order an adult long leg. When I opened the product up I could tell it would not even fit over my arm. The company will not take back an unused product, Even though I barely opened it up.They are not easy to deal with. Form responses are all I really get from them. To shorten a long story, don't deal with Active Forever there are many other medical appliance companies out there. Save your money and get things from a company whose products better fit the the description.
