Knowledge of High Heel Materials and Components: The Risks of Formaldehyde & Chromium VI and SAINIYA’s Safe Solutions

Why Pay Attention to High Heel Materials?

In today’s fashion world where style and comfort coexist, high heels are not only a classic wardrobe essential but also items that stay in close contact with the skin. During production, materials may contain formaldehyde and chromium VI, which pose health risks with long-term wear.
This article explains the knowledge of high heel materials and introduces how SAINIYA ensures safety and comfort through eco-friendly practices.

Common Types of High Heel Materials

  • Genuine leather (Chrome-tanned leather): Luxurious texture, but may generate chromium VI during the tanning process.

  • Synthetic leather (PU, PVC): Shiny appearance, but may contain plasticizers and residual solvents.

  • Textiles (cotton, polyester, nylon): Lightweight and breathable, but finishing agents may contain formaldehyde or PFAS.

Potentially Harmful Substances in High Heel Materials

Formaldehyde
