NIB Timberland 3 Eye Boat Shoes Sz 10 -color: burgundy The premium full-grain leather upper of this shoe provides comfort, durability and abrasion-resistance, while the hardware is corrosion-resistant and will stand the test of time. The 360-degree rawhide lacing system allows for a custom fit. The upper is stitched to the EVA midsole, which is then cemented to the outsole with no exposed stitching. There is an EVA-filled heel and forepart for lightweight comfort, and an airport-friendly nylon shank that will not set off metal detectors.
