A boot is a type of footwear. Most boots mainly cover the foot and the ankle, while some also cover some part of the lower calf. Some boots extend up the leg, sometimes as far as the knee or even the hip. Most boots have a heel that is clearly distinguishable from the rest of the sole, even if the two are made of one piece. Traditionally made of leather or rubber, modern boots are made from a variety of materials.
Boots are worn both for their functionality and for reasons of style and fashion. Functional concerns include: protection of the foot and leg from water, mud, pestilence (infectious disease, insect bites and stings, snake bites), extreme temperatures, sharp or blunt hazards (e.g. work boots may provide steel toes), physical abrasion, corrosive agents, or damaging radiation; ankle support and traction for strenuous activities such as hiking; and durability in harsh conditions (e.g. the underside of combat boots may be reinforced with hobnails).
In some cases, the wearing of boots may be required by laws or regulations, such as the regulations in some jurisdictions requiring workers on construction sites to wear steel-toed safety boots. Some uniforms include boots as the regulated footwear. Boots are recommended as well for motorcycle riders. High-top athletic shoes are generally not considered boots, even though they do cover the ankle, primarily due to the absence of a distinct heel. In Britain football (soccer) cleats are also called boots.
Early boots consisted of separate leggings, soles, and uppers worn together to provide greater ankle protection than shoes or sandals. Around 1000 BC, these components were more permanently joined to form a single unit that covered the feet and lower leg, often up to the knee. A type of soft leather ankle boots were worn by nomads in eastern Asia and carried to China to India and Russia around AD 1200 to 1500 by Mongol invaders. The Inuit and Aleut natives of Alaska developed traditional winter boots of caribou skin or sealskin featuring decorative touches of seal intestine, dog hair and suchlike. 17th century European boots were influenced by military styles, featuring thick soles and turnover tops that were originally designed to protect horse mounted soldiers. In the 1700s, distinctive, thigh-high boots worn by Hessian soldiers fighting in the American Revolutionary War influenced the development of the iconic heeled cowboy boots worn by cattlemen in the American west.
Boots which are designed for walking through snow, shallow water and mud may be made of a single closely stitched design (using leather, rubber, canvas, or similar material) to prevent the entry of water, snow, mud or dirt through gaps between the laces and tongue found in other types of shoes. Waterproof gumboots are made in different lengths of uppers. In extreme cases, thigh-boots called waders, worn by anglers, extend to the hip. Such boots may also be insulated for warmth. With the exception of gum boots, boots sold in general retail stores may be considered "water resistant," as they are not usually fully waterproof, compared to advanced material boots, such as Gore-Tex, used regularly by fishers or hikers.
Speciality boots have been made to protect steelworkers' feet and calves if they accidentally step in puddles of molten metal, to protect workers from a variety of chemical exposure, to protect workers from construction site hazards and to protect feet from extreme cold (e.g., with insulated or inflatable boots for use in Antarctica). Most work boots are "lace ups" made from leather. Formerly they were usually shod with hobnails and heel- and toe-plates, but now can usually be seen with a thick rubber sole, and often with steel toecaps. While gumboots are often used in workplaces, such as underground mines, studies have shown that workers prefer "lace up" boots mainly due to their support and better fit.
Boots are normally worn with socks to prevent chafes and blisters, to absorb sweat, to improve the foot's grip inside the boot, or to insulate the foot from the cold. Before socks became widely available, footwraps were worn instead.
Bovver boots, Doc Martens boots and army boots were adopted by skinheads and punks as part of their typical dress and have migrated to more mainstream fashion, including women's wear. As a more rugged alternative to dress shoes, dress boots may be worn (though these can be more formal than shoes). Fashionable boots for women may exhibit all the variations seen in other fashion footwear: tapered or spike heels, platform soles, pointed toes, zipper closures and the like. The popularity of boots as fashion footwear ebbs and flows. Singer Nancy Sinatra popularized the fad of women wearing boots in the late 1960s with her song "These Boots Are Made for Walkin'". They were popular in the 1960s and 1970s (particularly knee-high boots), but diminished in popularity towards the end of the 20th century. In the 2010s, they experienced a resurgence in popularity, especially designs with a long bootleg.[vague] Boot bolos, boot bracelets, boot straps, boot chains, and boot harnesses are used to decorate boots. Sandal boots also exist.
Boots have become the object of sexual attraction for some people and they have become a standard accessory in the BDSM scene (where leather, latex and PVC boots are favoured) and a fashion accessory in music videos. Knee- or thigh-high leather boots are worn by some strippers and pornography models and actresses. Boots have even become a sexual fetish for devotees known as boot fetishists and foot fetishists.

Because of the origin of heraldry as insignia used by mounted warriors like the medieval knights, when boots are used in heraldry, they are often displayed as riding boots, even if the blazon might not specify it as such. They are sometimes adorned with spurs, which may or may not have another tincture (colour) than the boot and the background field.
