Abstract: A pet cushion comprises a cushioning element including an elastomeric material layer and at least one foam layer coupled to the elastomeric material layer. The elastomeric material layer includes a plurality of intersecting buckling walls defining hollow columns therebetween. An interior cover, which is impermeable to liquid, encloses the cushioning element. An exterior cover encloses the first cover and the cushioning element. The exterior cover comprises a material different from a material of the interior cover.

Abstract: An insole for a shoe includes an insole body of elastomeric material having a first major surface and a second major surface opposite the first major surface. A distance between the first major surface and the second major surface is between about 1 mm and about 10 mm. The elastomeric material defines a plurality of voids extending through the elastomeric material from the first major surface to the second major surface. Each void has a dimension between about 1 mm and about 3 mm in a plane parallel at least one of to the first major surface and the second major surface. A minimum distance between adjacent voids is between about 0.5 mm and about 3 mm. A shoe insole includes such a cushion. A method of forming an insole for a shoe includes providing an elastomeric material within a mold to form an insole body of elastomeric material.
