Abstract: A slipper sock having a rubber sole liner. The lining is formed by embedding the sock within uncured, liquid latex rubber. The liquid rubber is prevented from embedding a central zone on the sole of the sock, but embeds fabric of the sock at the periphery of this zone. This is preferably accomplished by spraying a coagulant upon the sole of the sock, which causes immediate, localized curing of the uncured latex which then cannot permeate through the sock fabric. The liner thus is securely bonded to the sock. The sock has a sole comprising fabric unencumbered by rubber, thereby presenting a fabric material to the sole of a wearer's foot. The liner protects the fabric sole from abrasion and protects the wearer's foot from sharp objects and extreme temperatures, while the liner remains physically separate and apart from the fabric sole.
