Crafted of Horween Chromexcel® American Bison with vegetable-tanned steer leather trim. Tubular moccasin construction feels slipper-soft and flexible, with a more structured rubber sole that enhances walking comfort and durability. Foam-cushioned insole with microfiber/leather lining provides enhanced moisture-wicking properties and breathability for barefoot comfort. Runs a half size big, so if you are a 10, order a 9.5.
