Cowboy boots refer to a specific style of riding boot, historically worn by cowboys. They have a Cuban heel, rounded to pointed toe, high shaft, and, traditionally, no lacing. Cowboy boots are normally made from cowhide leather but are also sometimes made from "exotic" skins such as alligator, snake, ostrich, lizard, eel, elephant, stingray, elk, buffalo, and the like.
There are two basic styles of cowboy boots, western (or classic), and roper. The classic style is distinguished by a tall boot shaft, going to at least mid-calf, with an angled "cowboy" heel, usually over one inch high. A slightly lower, still angled, "walking" heel is also common. The toe of western boots was originally rounded or squared in shape. The narrow pointed toe design appeared in the early 1940s.
A newer design, the "roper" style, has a short boot shaft that stops above the ankle but before the middle of the calf, with a very low and squared-off "roper" heel, shaped to the sole of the boot, usually less than one inch high. Roper boots are usually made with rounded toes, but, correlating with style changes in streetwear, styles with a squared toe are seen. The roper style is also manufactured in a lace-up design which often fits better around the ankle and is less likely to slip off, but lacing also creates safety issues for riding.
Riding boots had been a part of equestrian life for centuries. Until the industrial age, boots were individually handmade in many different styles, depending on culture. Early cowboy boot designs, along with other cowboy accoutrements, were also heavily influenced by the vaquero tradition imported from Spain to the Americas, dating back to the early 16th century. Military boots designed for cavalry riders also had an influence.
