This multilayer low friction pad for reducing shear and friction forces on a person's body, and for preventing and treating sores on a person's body caused by shear forces, friction, pressure, chafing and moisture, has a first layer made of soft, flexible foam material which is thick enough to serve as a shock absorber, facilitate handling, and prevent wrinkling and crumpling of the pad. A second layer bonded to the foam layer has a very slippery surface on which is a third layer composed of a slippery lubricant cooperating with the second layer to reduce shear forces and provide a working surface having a negligibly small coefficient of friction. The first layer has an exposed side rough enough to prevent frictionally displacement of the pad while in use. A nonporous fourth layer can be bonded between the first and second layers to serve as a moisture barrier. One or more drain holes can be provided in the pad underlaid by a highly absorbent mat attached to the exposed side of the first layer. The pad can be shaped as a cap, sock, glove, etc. to fit on a body part to be protected from shear forces, friction, pressure, chafing and moisture.
