HOBNAIL
Hobnail is a type of nail that has a large, round head made of metal, typically used to provide a non-slip grip on footwear such as boots or work shoes. The term "hobnail" is also used to describe the pattern of bumps or studs that are created on the sole of a shoe using hobnails. Hobnail boots were traditionally worn by workers in fields or other rough terrain, as the hobnails provided extra traction and protection against wear and tear. Nowadays, hobnail footwear is still used in certain industries such as construction or agriculture, as well as being popular in some fashion styles.
