Examples of sustainable materials and processes currently used in ASICS products include recycled polyester, bio-based materials and solution dyeing.

1. Recycled polyester

We’re committed to supporting a circular economic model where resources are reused and recycled rather than being sent to landfill.  ASICS is committed to replace polyester materials in shoe uppers and sportswear products with 100% recycled polyester by 2030.

2. Bio-based materials: Cellulose nanofiber (CNF)

Launched in 2018, the GEL-KAYANO™ 25 is the world’s first running shoe to feature cellulose nanofiber (CNF). CNF is a nano-sized ultra-fine fiber made from plant biomass that is one-fifth the weight of steel but five times stronger.

3. Solution dyeing

A process that uses around 50% less water than conventional dyeing methods. Instead of introducing dyes by dipping and washing of fabrics, the new process adds color to the synthetic fiber components in their liquid state before the fiber is actually produced.
