Conformable booties, shoe inserts, and footwear assemblies made therewith, and waterproof breathable socks

This invention describes a special kind of waterproof, breathable inner layer for shoes, called a bootie. It's made from a single, stretchy piece of a material called ePTFE, which is then combined with fabric. This seamless design means it can be molded to fit many different shoe sizes and shapes without needing separate sizes or waterproof tape.
