When sourcing women's slippers, the choice of material directly impacts comfort and durability. For the upper, Coral Fleece, Faux Fur, and Genuine Suede are popular for luxury and warmth, while Linen and Cotton are preferred for breathability in summer styles. The outsole must be made of TPR (Thermoplastic Rubber) or EVA (Ethylene Vinyl Acetate) to ensure a non-slip grip, flexibility, and lightweight performance. For premium markets, ensure the use of High-Density Memory Foam (at least 40D) in the insole to provide long-lasting cushioning and prevent flattening.
