We use natural latex in our gum rubbers, 30% recycled material in all our outsoles, and 100% recycled material in our packaging. We source all of our leathers exclusively from environmentally conscious ISO-14001 certified tanneries. We are exploring water-based glues, however, at this time the sub-par bond durability outweighs the benefits. We will make the switch once the bonding strength improves. We consider making high-quality, long-lasting footwear as one way to reduce our environmental footprint.
