Cowboy boots refer to a specific style of riding boot, historically worn by cowboys. They have a high 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, sting ray, elk, buffalo, and the like.
Half boots vary in length, anywhere from around the mid point of the lower leg, to around three-fourths of the lower leg (this coincides with the mid-calf, the part of the calf with the largest circumference). For comparison, half-boots are generally fall within the same length range as trouser socks. Generally, crew length and shorter boots are just referred to as boots, whereas longer boots are knee boots and higher.
Kneehigh boots are boots that rise up to, but not including, the knee, or slightly thereunder; they leave the knee exposed. Boots that partly cover the knees, or fully cover and extend above the knees, are thigh boots / over-the-knee boots. Boots at a trouser length (or shorter) are half boots (or lower).
Rubber boots are waterproof boots made of rubber. They are commonly used for a range of pursuits, generally agricultural and outdoors in nature, in which waterproofing one's feet and ensuring traction with the ground is paramount, generally under very damp conditions. Such conditions may include heavy rain, permanently wet terrain such as marshes, fishing boats, certain types of industrial plants, or even camping.
Thigh boots and over-the-knee boots are boots that either: fully cover and extend above the knees, or partly cover the knees, leaving only the thigh area exposed. Boots that rise up to, but not including, the knee, or slightly thereunder, are kneehigh boots.
