The Wolverine Corsair 6'' Boots feature waterproof full grain leather uppers with ArmorTek guard. Armortek guard is an extra abrasion-resistant texture on the boots upper that prevents wear and tear, especially on the toe area. The Wolverine Corsair boots also feature the Contour welt construction which provides the flexibility and comfort of athletic shoes with the support and durability of work boots. There are individual compression pads on the sole that absorb shock and return energy. Also, the welt design allows the boots to flex and bend at essential points for maximum performance. This is also a composite safety toe boot which makes the Corsair a lighter weight boot with all the protection of a steel safety toe boot. Material: Leather, Mesh, Rubber.
