Which is better: a rubber sole or a PVC sole?

Summary Description:

Overall, PVC soles and rubber soles each have their own advantages and disadvantages, and they are suited to different types of footwear: PVC soles are ideal for fashion shoes, while rubber soles are better for athletic shoes.

PVC material boasts adjustable physical properties and is easy to mold. PVC soles are characterized by their low density, lightweight construction, excellent elasticity, ease of coloring, good breathability, and high strength. They are commonly used in leather shoes, children’s athletic shoes, and fashion footwear.

 

Rubber soles are a type of polymer, available in both natural and synthetic forms. Common rubber outsoles are known for their soft feel, excellent elasticity, good abrasion resistance, and resistance to acids and alkalis, making them widely used in various types of athletic footwear. However, rubber soles also have drawbacks: they tend to be relatively heavy, prone to blooming, and comparatively expensive.

 

Rubber soles are a very traditional type of sole, relatively old in design, yet they excel in wear resistance and high-temperature durability; meanwhile, PVC soles are a modern material that is lightweight and easy to mold.

Rubber is a natural material, sourced directly from nature, which makes it environmentally friendly. For this reason, it is often used for the soles of safety shoes. Because natural rubber soles tend to be quite dense, they can make the shoe relatively heavy. Coupled with the specific requirements of safety footwear, the finished pair can end up being rather weighty. Nevertheless, in many situations, this type of safety shoe remains a popular choice due to its excellent wear resistance and slip‑resistance.

PVC soles originated in Germany during World War II. PVC is an environmentally friendly material that readily hydrolyzes, yet exhibits excellent physical properties under normal drying conditions. First and foremost, it is lightweight and easy to foam‑mold, allowing for spray‑coating in a wide range of colors. It also offers good abrasion and flex resistance, making it well suited for sandals, beach shoes, and casual footwear. Because standard PVC materials have somewhat limited low‑temperature resistance and slip‑resistance, many cotton‑lined PU‑V sole applications are reinforced with TPR or PVC “tendon” inserts. Clearly, safety shoe soles made from PVC are exceptionally light, fully meeting customer demands for lightweight designs. However, given that safety shoes are specialized products often equipped with steel toe caps and midsoles, the market for lightweight safety footwear remains substantial.

Overall, PVC soles and rubber soles each have their own advantages and disadvantages, and they are suited to different types of footwear: PVC soles work best for fashion shoes, while rubber soles are ideal for athletic shoes.

Things to keep in mind when choosing shoes for young children: 
Shoes that are too small can squeeze the feet, leading to foot deformities, while shoes that are too large may easily slip off during walking, which is very inconvenient. Meanwhile, shoes that fit just right may not accommodate the continuous growth and development of a child’s bones. Therefore, it is recommended to choose children’s shoes that are slightly larger.
