which comprises:

having a melting temperature of 135°C or above substantially
uniformly throughout an elastomeric matrix;
applying at least one coating of said microsphere
containing matrix at a substantially uniform thickness to a
surface of a base fabric ply to form a coated base fabric ply;
and
vulcanizing said coated base fabric ply at a temperature
of 80-150°C for a time of between about 1 and 6 hours to
substantially fix the position of said high melting
thermoplastic microspheres within said matrix and form a
compressible layer such that said microspheres provide
substantially uniform compression characteristics to said
layer.
Claims 1 through 8, 12 through 20, 23, 24, 26 through 29,
