The V-shaped top cut of the boot is a distinctive feature of the appearance of cowboy boots, which originated from the Hessian boot in Germany and was introduced to the United States by Hessian mercenaries who participated in the American Revolution in the late 18th century. Early cowboy boots were all made of full leather without decorative patterns. Later, at the request of the maker, shoemakers began to add embroidery and sewing with different patterns to the product, mostly focusing on the design of the boot barrel. The pleasing degree of the pattern has become an important indicator determining the value of a pair of denim boots.
