Breathable and waterproof footwear

This invention describes a shoe designed to be both waterproof and breathable. It uses an inner functional layer, like a membrane, suspended within the shoe's outer material. This inner layer is anchored by adhesive and stitched to the shoe's insole or sole, creating a sealed, breathable inner bootie. The claims specifically define this functional layer as waterproof and breathable, with its lower end attached to the sole.
