A new rugged-casual classic with legendary Børn comfort. You’ll love the relaxed unstructured look, soft, distressed leathers and zip-on ease of the Sienna ankle boot. TruOpanka: Our patented handcrafted construction process is designed for ultimate flexibility. The upper, cushioning foam insole and outsole are stitched together by hand, reducing the need for extra layers that make other shoes stiff. It’s the foundation of every Børn shoe and what makes our footwear so comfortable.
