Rackle manufactures a more earth-friendly shoeRackle's mission is to produce the most comfortable, sustainable, and biodegradable lightweight shoes that naturally help reduce your carbon footprint. Rackle was built on the principle of developing earth-friendly footwear to help lessen the shoe industry's impact on the planet. Today, about 300 million shoes are thrown away each year in the USA alone. Rackle shoes are designed using sustainable hemp and rapidly-biodegradable soles that begin to breakdown 30-50 times faster than ordinary foam soles.
