Ostrich is one of the most versatile hides that we utilize. It is extremely soft, but as strong as alligator. We use no synthetic material and every part of it is handmade (which is why this boot will last a lifetime). Lux-calf interior for glove-like comfort. Full leather insole (for breathability and custom shaping to your foot). 1.5 cowboy toe. Uppers have lone star ostrich inlay and 12 high. Heel is leather stacked 1 1/2. Soles are hand pegged with lemonwood. Width is d (normal) and the sizing is the industry standard (same as your shoes). Wider boot is ee. This item is made of ostrich and leather.
