1. A web of shoe covers comprising:
a first sheet member of polymeric material;
a second sheet member of polymeric material generally underlying the first sheet member, the first and second sheet members having opposite longitudinal edges and being operatively connected to each other at the respective longitudinal edges, the first and second sheet members having a length parallel to the longitudinal edges and a width transverse to the longitudinal edges that is less than the length of the first and second sheet members;
a first line of weakness extending between the longitudinal edges of the first and second sheet members at a first location, the first line of weakness being constructed to promote tearing of the first and second sheet members along the first line of weakness;
a second line of weakness extending between the longitudinal edges of the first and second sheet members at a second location, the second line of weakness being constructed to promote tearing of the first and second sheet members along the second line of weakness;
a first shoe cover defined between the first line of weakness and the second line of weakness adjacent to a first of the opposite longitudinal edges of the first and second sheet members;
a second shoe cover defined between the first line of weakness and the second line of weakness adjacent to a second of the opposite longitudinal edges of the first and second sheet members;
a third line of weakness extending between the first line of weakness and the second line of weakness, the third line of weakness defining a boundary between the first shoe cover and the second shoe cover;
an upper seal operatively connecting the first sheet member and the second sheet member, the upper seal extending generally between the first line of weakness and the second line of weakness, the upper seal and third line of weakness cross over each other between the first line of weakness and the second line of weakness.
