Since 1906. Protects against water and dirt. Nano technology. Kiwi Super Protector offers superior protection to keep shoes looking great longer (tested against regular Kiwi Protect-all formula) by creating an extra strong invisible shield that helps prevent water and dirt from penetrating leather, suede, nubuck, fabric and textile footwear, while allowing it to breathe. Great for shoes, boots, athletic footwear, and other leather articles such as jackets, coats, bags, hats, ski wear and best results, reapply every 8-10 wearings.
