A new light foamed structure is provided. The structure comprises a top layer, a middle layer, a bottom layer, and glue, wherein the middle layer comprises essentially elastic material and the top and bottom layers comprise essentially un-strethable meterial. The glue is strongly adherent to the top and bottom layers to the middle layer, wherein the strength of the adherence being a result of at least the pressing of the top layer and the bottom layer toward each another, to a roughly 1 -40% distance of the top layer from the bottom layer compared to the distance before the pressing. After pressing, the distance regains its distance before pressing occured. |
