What is salt-resistant leather and how does it work?
Salt-resistant leather is treated to resist the white staining, drying, and cracking that road salt causes in conventional leather. ISA TanTec, a business unit of ISA Next-Gen Materials, offers salt resistance as a finishing option so footwear keeps its appearance and durability through winter wear and heavy use.
