Reversible Multi-Purpose Liner

Abstract

A multi-sided, multi-purpose liner is provided for use in footwear. Each side of the liner provides one or more benefits to the wearer. The liner is reversible, such that a first side with a first benefit can contact the wearer's foot or a second side with a second benefit can contact the wearer's foot. The wearer can flip or rotate the liner so that the side having the desired benefit contacts their foot during use. One side of the liner may include a plurality of benefits in a preselected pattern across the surface. A liner kit provides a material blank from which the liner may be cut to produce a desired distribution of benefits. The benefits of the liner may vary with respect to the location on the surface of the liner, with some areas of the liner displaying an increased or decreased degree of a specific benefit.
