Molding the liner to have a gel cushion layer on its interior surface with the gel passing through and embedding the at least one intermediate fabric section therein to form at least one annular seal. The intermediate fabric section selected of meltable fibers and knit construction that may or may not be melted by the gel during the molding process whereby the at least one annular seal is not inhibited in compression and/or elongation by the presence or absence of fabric when the liner is worn thereby reducing or eliminating any discomfort of the liner during ambulation caused by the annular seal.
