Full-grain Leather

This type of leather retains the top or outer surface of the hide, which contains dense, tight fibers that are water-resistant and supportive. With shoes and boots, it conforms well to the foot over time, can be waterproofed, is abrasion-resistant, and will last for years when properly cared for. If this surface faces outward, it is called smooth-out. When it faces inward, rough-out leather protects the tighter fibers of the top grain from abrasion (giving the leather a longer functional life). Full grain leather can vary in thickness, depending on the starting thickness of the hide and on what part of the hide the leather is taken from. Thicker leathers require longer to break in, but make a more durable, supportive boot. Some footwear is made with thicker leather only in the high-wear, high-support areas, and thinner, lighter, and more breathable leather in the remaining sections.
