Classic Indie Zebra is a modern classic with its clean lines and sophisticated styling. A great new natural rubber boot for all seasons! The lining is synthetic, meaning the boots dry quickly, so you can soon put them on again even if the puddles were too deep! Like all other Viking rubber boots, this boot is made with natural rubber. Inside there is a removable insole you can take out to dry. All Viking rubber boots are handmade, and in natural rubber. Handmade, PVC free and vegan.
