The Birkenstock Bryson Shearling Oiled Nubuck Leather Graphite boot is a cozy, casual lace-up built for cold seasons. It features an oiled, water-repellent nubuck leather upper that develops a rich, unique patina over time. The interior is fully lined with plush shearling for warmth and soft comfort. A removable cork-latex footbed supports natural alignment, while the lightweight TR (thermoplastic rubber) sole provides everyday traction. Made in Portugal, this boot combines Birkenstock’s iconic footbed design with a rugged, yet refined aesthetic.
