The flooring (1), preferentially designed to be used for laying running tracks, comprises a treading layer (2), constituted by an elastomer mass and a supporting layer (3), which is also constituted by an elastomer mass. The supporting layer (3) has, on the side opposite to the treading layer (2), an array of cavities (5) delimited by ribbings (5a) constituting a mesh of uniform ribbings. The cavities (5) are cavities having an elongated shape in the direction of running (A) on the flooring (1). The cavities occupy a volume equal to at least 28%, and preferentially at least 30%, of the volume of the supporting layer (3). |
