PU leather, full name polyurethane synthetic leather, is a man-made synthetic material widely used in shoes, clothes, furniture and other fields. It has the advantages of being light, soft, wear-resistant and waterproof, but it also has disadvantages such as easy deformation, easy fading and easy dirtiness. When choosing PU leather shoes, you need to consider multiple factors to ensure that you buy a product that is both comfortable and durable. Here are some key points for selection:
Observe the appearance
Texture and color: PU leather can imitate the texture and color of various leathers or fabrics, but carefully observe whether its surface texture is uniform and natural. High-quality PU leather has clear texture and uniform color, while inferior products may appear blurry or unnatural.
Gloss: The surface gloss of PU leather should be moderate. Too shiny may mean that too much chemical coating has been added, which may affect its breathability and durability.
Check the touch
Softness: PU leather should be soft and elastic to the touch, but it should not be too soft or too hard. Press the upper with your fingers and observe its recovery speed. High-quality PU leather should be able to return to its original state quickly.
Thickness and uniformity: Check whether the thickness of the upper material is uniform, and avoid choosing products with different thicknesses, as this may affect the overall comfort and durability of the shoe.
Smell
Pungent odor: PU leather usually has a slight plastic smell, but if the smell is too pungent or does not dissipate for a long time, it may be that inferior materials or too many chemical additives are used.
Test wear resistance
Friction test: Gently scratch the upper with your fingernails or hard objects to see if it is easy to leave scratches. High-quality PU leather should have good wear resistance and not be easily scratched.
