Mass production is another advantage of pu leather. Factories can make large quantities quickly, so you get more choices in color, texture, and design. The benefits of pu leather include affordability, easy care, and ethical appeal.

Disadvantages of PU Leather

You should also consider the cons and drawbacks of pu leather. One of the main disadvantages of pu leather is durability. Many people ask, is pu leather durable? While pu leather can look good at first, it does not last as long as real leather. Polyurethane coatings can develop hairline cracks and start to peel within 18 months. This problem, called hydrolysis-related failure, often leads to larger cracks and flaking.

"Although not common, it has come to our attention that some of our customers are reporting that, over time, certain Durablend® products have experienced cracking, peeling and flaking."

Another drawback of pu leather is breathability. Shoes and accessories made from pu may not let your skin breathe as well as real leather. This can make them less comfortable in hot weather.

Environmental impact is also a concern. Even though pu leather is vegan, it uses petroleum-based chemicals. The production process can release volatile organic compounds, which affect air quality.

If you wonder, is pu leather durable for daily use, you may find that it works well for a short time but does not match the lifespan of real leather. The cons of pu leather include possible cracking, lower breathability, and environmental drawbacks. You should weigh these disadvantages of pu leather before making a purchase.

PU Leather Upper vs Real Leather

Appearance and Feel

When you compare pu leather upper to real leather, you notice clear differences in texture and look. Pu leather gives you a uniform surface with consistent coloring. Real leather shows natural grain variations and small imperfections. Over time, real leather develops a unique patina, while pu leather keeps its factory appearance. If you inspect the edge, pu leather reveals a fabric backing, but real leather shows fibrous layers.

You also feel a difference when you touch each material. Real leather feels warm, stretches, and wrinkles like skin. Pu leather feels cold and returns to its original shape after bending.
