An insole for a shoe, comprising: an insole body comprising elastomeric material having a first major surface and a second major surface opposite the first major surface , wherein a distance between the first major surface and the second major surface is between 1 mm and 10 mm; wherein the elastomeric material comprises an A-B-A triblock copolymer and a plasticizer, wherein a ratio of a weight of the plasticizer to a weight of the triblock copolymer is from 0.1 to 50; wherein the elastomeric material defines a plurality of voids extending through the elastomeric material from the first major surface to the second major surface , wherein each void of the plurality has a dimension between 1 mm and 3 mm in a plane parallel to at least one of the first major surface and the second major surface ; and wherein a minimum distance between adjacent voids of the plurality is between 0.5 mm and 3 mm, preferably between 0.8 mm and 1.5 mm; wherein a volume of the voids is between 25% and 40% of a volume between the first major surface and the second major surface ; wherein the thickness of the insole body, the maximum dimension of the voids , and the minimum distance between adjacent voids are selected such that when a force is applied to the insole body in a direction perpendicular to the first major surface , a portion of the elastomeric material bulges to deform or collapse voids in a vicinity of the applied force before the first major surface bottoms out against the second major surface the voids being large enough to allow the elastomeric material to bulge, but too small for the elastomeric material to buckle. an insole body comprising elastomeric material having a first major surface and a second major surface opposite the first major surface , wherein a distance between the first major surface and the second major surface is between 1 mm and 10 mm; wherein the elastomeric material comprises an A-B-A triblock copolymer and a plasticizer, wherein a ratio of a weight of the plasticizer to a weight of the triblock copolymer is from 0.1 to 50; wherein the elastomeric material defines a plurality of voids extending through the elastomeric material from the first major surface to the second major surface , wherein each void of the plurality has a dimension between 1 mm and 3 mm in a plane parallel to at least one of the first major surface and the second major surface ; and wherein a minimum distance between adjacent voids of the plurality is between 0.5 mm and 3 mm, preferably between 0.8 mm and 1.5 mm; wherein a volume of the voids is between 25% and 40% of a volume between the first major surface and the second major surface ; wherein the thickness of the insole body, the maximum dimension of the voids , and the minimum distance between adjacent voids are selected such that when a force is applied to the insole body in a direction perpendicular to the first major surface , a portion of the elastomeric material bulges to deform or collapse voids in a vicinity of the applied force before the first major surface bottoms out against the second major surface the voids being large enough to allow the elastomeric material to bulge, but too small for the elastomeric material to buckle. <EOS>
