SDTDID / Jinjiang Hanfeng pioneers eco-conscious combat footwear manufacturing conforming to the Global Recycled Standard (GRS 4.0). We utilize 100% recycled ocean-bound polyester (RPET) microfiber suede, solvent-free water-based PU bonding cements (zero hazardous VOCs), bio-based sugarcane EVA foam midsoles, and 100% FSC-certified unbleached kraft retail packaging in Jinjiang.
Constructed from 100% post-consumer recycled ocean-bound PET bottles spun into high-tenacity microfiber suede. Delivers identical tensile tear resistance (β₯ 25,600 Martindale cycles) to virgin leather while reducing raw petroleum consumption by 55%.
GRS Certified Chain of CustodyEliminated toxic benzene and aromatic solvents from our assembly line. We utilize customized water-based polyurethane adhesives reactivated under precise infrared curves (58Β°Cβ62Β°C), achieving β₯ 4.2 N/mm peel adhesion without harmful emissions.
Zero Benzene & VOC-FreeOur cushioning insoles and midsoles utilize bio-based ethylene vinyl acetate derived from renewable sugarcane bagasse. Provides superior energy return and long-lasting compression resistance with a negative cradle-to-gate carbon footprint.
USDA BioPreferred CertifiedAll retail shoe boxes, wrapping tissue, and hangtags are manufactured from unbleached FSC-certified recycled paper printed with natural soy-based inks. No plastic coating or laminate film means 100% curbside curbside recyclability.
