Earth Spirit is an American brand that was introduced into the UK over 9 years ago. They only produce leather footwear, which is sourced from the companies own tanneries, guaranteeing consistency of quality. Gelron 2000 memory foam is widely used in production. It is either in the contoured footbeds or arch supports. Environmental issues are considered with every new design – recycled milk cartons are used to make insole boards, all packaging is glue-free and printed using soy based inks, and all waste water is fully treated to be made environmentally safe.
