If the upper of the shoe is made of synthetic materials, the decomposition of the shoe will be even longer. So far, the only exception to the mass-produced sole materials is reactive polyester polyurethane, which can decompose due to microbes and moulds in about 25 years.

Our biodegradable footwear is made only of such biodegradable materials - polyurethane skeleton, sandwich part , degradable foam latex, cotton and linen insole, bio heel material and only natural cow, goat and sheep leather.
