3 Different Shoe Sole Material Types

Rubber

  • Rubber is a commonly used sole material. It is a polymer compound that can be either natural or synthetic.
  • Disadvantages:Heavy, not environmentally friendly (difficult to decompose when discarded), poor breathability, poor moisture absorption, susceptible to oil damage.
  • Advantages: Good abrasion resistance, slip-resistant, elastic, not prone to breakage.
  1. Often used as the material for rain boots.
  2. Also used as sole material for athletic shoes.

EVA

  • EVA is a lightweight, flexible, and highly shock-absorbent material. It is a type of polymer material.
  • Advantages: Lightweight, soft, elastic.
  • Disadvantages: It may harden over time. In my experience, it is commonly used as the standard material for Noiseless Household Slippers. 

TPR

  • TPR (Thermoplastic Rubber) is a synthetic rubber material known for its excellent grip and durability.
  • Advantages:
  1. Good abrasion resistance: TPR material has excellent resistance to wear and can withstand friction and abrasion during daily use, prolonging the lifespan of the shoe sole.
  2. Good elasticity and cushioning: TPR material provides good elasticity, offering comfortable cushioning and support to reduce impact and pressure during walking or running.
  3. Good slip resistance: TPR material typically has good slip resistance, providing reliable traction and stability to reduce the risk of slipping and falling.
  • Disadvantages:
  1. Relatively heavy: Compared to some other sole materials, TPR material may be relatively heavy, adding some weight to the wearer.
  2. Not suitable for extreme temperatures: The performance of TPR material can be affected in extreme high or low temperature environments, leading to hardening or softening, which may affect the lifespan and performance of the shoes.
