Raw, rugged and worn-in from the first step. These shoes are crafted from tumbled Ambassador leather, which retains its natural characteristics and markings, and ages uniquely with wear. Built on a tough-as-nails AirWair sole, the shoes are reinforced with our signature yellow welt stitch. Ambassador - A heavyweight and oily leather that’s been tumbled for added character. Wipe away dirt using a damp cloth. Apply to the outside of your footwear to keep the leather supple Goodyear Welted - the upper and sole are heat-sealed and sewn together, providing more comfort and durability for years to come.
