Insoles
Conventional Insoles
Conventional midsoles and insoles are environmentally harmful made petroleum-based foam. Plastic shoe insoles contribute to the global microplastic crisis and health concerns in two major ways: environmental micro-pollution from degradation and abrasion, and direct exposure to toxic chemicals that leach into the skin through prolonged wear.
- ❌ Petroleum-based foam: The majority of mass-market insoles are manufactured using synthetic petroleum-based plastics
- ❌ Ethylene-Vinyl Acetate (EVA) foam: synthetic petroleum-based plastics
- ❌ Polyurethane (PU): synthetic petroleum-based plastics
- ❌ Pollution: The Global Scale 44 Billion Discarded Insoles
Conventional Insoles
Avoid Greenwashing insoles made by brands that pretend to be sustainable, eco-friendly, and claim to be made with safer materials when they are not. They will use misleading marketing claims to convince you to buy their products. Many came with vegan leather alternatives, bringing more plastic to the world:
- ❌ PVC: Most vegan leathers today are made from PVC, made with petroleum. PVC is, for this reason, harmful to the environment.
- ❌ PU: is another synthetic vegan or faux leather. By definition, PU stands for Polyurethane, a plastic polymer derived from petroleum. Even less than PVC, PU still requires petroleum.
- ❌ Toxic dyes: toxic to the workers and the environment.
