1.Natural Rubber
Features: Extracted from the sap of rubber trees, it is a traditional yet high-performance material for rain boots.
2.PVC (Polyvinyl Chloride)
Features: The most common cost-effective synthetic plastic material.
3. EVA (Ethylene Vinyl Acetate)
Features: A lightweight foamed material that is often mistaken for rubber.
4.PU (Polyurethane)
Features：Lighter and more flexible than PVC, it boasts a more premium texture and is often used to make stylish rain boots with a leather-like appearance. However, its hydrolysis resistance varies; inferior products are prone to hydrolysis and chalking.
5.Rubber-blended Material
Features：Many brands adopt a hybrid formula of natural rubber and synthetic rubber, which achieves a better balance among cost, elasticity, durability and weight. It has become the mainstream choice for mid-to-high-end rain boots.
6.Textile + Waterproof Coating
Features：Fabrics such as canvas or nylon are coated with a waterproof layer (e.g., GORE-TEX), achieving a balance between waterproofing and breathability. This material is more suitable for prolonged wear scenarios like outdoor hiking, but it usually comes at a premium price.
