TPU-Bio Outsole
& Accessories
Bio-based. Slip resistant. Built for the demands of professional safety footwear.
Same performance.
Fossil-free origin.
A sustainable alternative to traditional fossil fuel-based TPU. Made with renewable natural resources like corn, wheat, or potatoes — offering the same performance characteristics as conventional TPU while contributing to reduced reliance on fossil fuels and lower greenhouse gas emissions.
Kessin TPU-Bio lightweight outsole provides excellent slip resistance (EN ISO 20345 SRA SRB), flexibility, and durability.
