• a plurality of blocks each arranged in one of the protrusion spacings, or adjacent to a single one of the protruding sections, the blocks being arranged so that at least a portion of sidewalls of each block protrudes above the end section or sections of the adjacent protruding section or sections of the base portion;
• and
• a plurality grooves are arranged between the blocks, each groove being defined by the end section of the one of the protruding sections of the base portion, as a groove bottom, and adjacent sidewalls of the blocks arranged in the protrusion spacings on each side of the respective protruding section and protruding above the end section,
• wherein at least one of the end sections is provided with first textures, and
