We use veg-tanned, full-grain leather soles for the majority of our shoes and boots. Not only do they look amazing, they are flexible and durable.   To make these soles, bovine leather bends are infused in a mix of chestnut, mimosa and quebracho which causes the leather fibers to slowly compress. This results in a robust and malleable, cellular structure. For some styles, we use SBR rubber soles for great traction and shock absorption. Our sneakers are outfitted with all natural rubber soles which resist wear and tear, provide great traction and are highly shock absorbent. Rubber soles are stitched-on as opposed to being glued or vulcanized.
