Claim:
1. A method for fabricating foot wear having a sole with a cork insert for use as a durable, walkable, wearable bottom surface on said foot wear, said method comprising: obtaining cork in raw sheet form; processing the raw sheet in a press; slicing the raw sheets into an intermediate cork sheet of predetermined thickness; adhering a thin fabric sheet to one side of the intermediate cork sheet using an adhesive, pressure roller and high temperature process rendering a cork/fabric sheet having a substantially planar cork surface on a first side and a substantially planar fabric surface on a second side; tracing sole patterns onto the cork/fabric sheet; cutting the sole patterns out of the cork/fabric sheet; inserting the cork/fabric sole pattern into a sole mold positioned with the cork surface adjacent a mold surface to prevent mold material from flowing onto the cork surface of the cork/fabric sheet; closing the mold and executing an injection cycle, wherein the injection cycle produces a finished sole with an outersole surface comprising: opening the mold and removing the finished sole; and attaching said finished sole to a foot wear upper; and wherein the outersole surface is the wearable bottom surface of the foot wear, and further wherein the exposed surface of the first portion of cork contacts the ground when the foot wear is worn.
