A shoe cover is a natural latex article with reduced amount of sulfur cross linking agent and accelerators including zinc dithiocarbamate that break catalytically soluble sulfur Ssulfur rings forming sulfur linear chains. Surfactants present in the pre-vulcanization composition wets natural polyisoprene particles and permeates small sized sulfur into the interior of these particles thereby pre-vulcanizing the particles. The latex emulsion also has post-vulcanization composition with accelerators that crosslink between particles during the post vulcanization cure cycle. The dipped natural polyisoprene article is substantially uniformly cured both in the inter-particle and intra-particle regions and reliably exhibits high cross link density, uniform distribution of double bonds and zinc segregation at the boundaries or original particles. The natural rubber films exhibit high tensile strength, tensile modulus, tear strength, elongation with low modulus of the shoe cover. The bottom surface of the shoe cover is etched to produce a slip resistant surface.
