The FBX Dr. Martens have the unique look and long lasting comfort that you know from Dr. Martens. These boots are made with heavyweight Grizzly leather. This is a full-grain leather with a subtle grained finish. It is comfortable and will quickly mold to your feet for a very individualized fit. The unique Flex Link technology in the outsole provides enhanced cushioning and flexibility. The sole is air-cushioned with internal technology which enables the sole to reflect the fore-foot's natural flex. The upper and the sole are sewn together, not just glued, like many footwear constructions. This, together with their Z welt-stitch and heat-sealing process, make them unique to Dr. Martens. These boots will last a long time and require only a small amount of care.
