A lightweight skid shoe assembly comprises a body of wear resistant, non-metallic or partially metallic material; and a structure coupling mechanism; wherein the body prevents friction-related damage to the structure. Another lightweight skid shoe assembly comprises a body of wear resistant, non-metallic or partially metallic material selected from the group consisting of: a polyamide or polyimide impregnated carbon fiber layup, a peek or PEI injection mold with carbon fiber, compression molded carbon fiber or fiberglass, a resin infusion with carbon fiber preform fabric, a fiber reinforced thermoset, acetal resin, machined acetal or thermoplastic, thermosetting plastic, or a metal-matrix composite; wherein the body prevents friction-related damage to a structure. Another lightweight skid shoe assembly comprises a body of wear resistant, non-metallic or partially metallic material; and a shear-bearing mechanism; wherein the shear-bearing mechanism directs shear forces away from the body; and wherein the body prevents friction-related damage to the structure.
