The calceus (pl.: calcei) was the common upper-class male footwear of the Roman Republic and Empire. Normally made of leather and hobnailed, it was flat soled and typically reached the lower shin, entirely covering the foot and ankle. It was secured with crossed thongs or laces. Equivalent to a short boot or high-top shoe, it was lighter than the military caliga but sturdier than slip-on shoes like the soccus and able to easily handle outdoor use.
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).
Caligae (Latin; sg.: caliga) are heavy-soled hobnailed military sandal-boots that were worn as standard issue by Roman legionary foot-soldiers and auxiliaries, including cavalry.
