[Hot Item] Double Layers PU Shoe Sole for Lady Sandals Slippers

PU (polyurethane) slipper soles offer advantages such as lightness, comfort, and wear resistance. However, they are also susceptible to moisture and hydrolysis, and may produce an odor. When choosing, pay attention to whether the material is double-sealed to ensure elasticity and comfort, and be mindful of whether it is too soft, resulting in high water absorption and odor.

Advantages of PU Slipper Soles

Lightness and Comfort: The lightweight material provides good elasticity and rebound, enhancing walking comfort.

Durability and Wear Resistance: Excellent wear and flex resistance, extending the lifespan of the sole.

Easy to Process: Easy to dye and mold, creating high-quality products and facilitating the design of various sole shapes.

Environmentally Friendly and Degradable: It can naturally decompose after disposal in landfills, minimizing environmental impact, hence the name "eco-friendly sole."

Disadvantages of PU Slipper Soles

Susceptibility to Moisture and Hydrolysis: In a humid environment, the molecular structure is easily brittle and broken down by contact with water molecules.
Odor: If the PU sole is too soft, it absorbs water easily and resists evaporation, leading to fungal growth and unpleasant odors.
High Cost: Compared to other materials such as EVA, PU is relatively expensive.
How to Choose the Right PU Slipper Sole
Considering Usage:
Comfortable Everyday Living: Choose a double-density PU material with good elasticity and softness, which provides good arch support and increased comfort.
Outdoor Activities: Choose a single-density PU material with good electrical insulation, wear resistance, and non-slip properties, which provides better protection.
Material Softness: Avoid overly soft single-density PU soles, as they absorb water easily and can easily produce odors.
Choose a flexible PU sole that is suitable for your arch support. Comfort and support are key.
