Sole (shoe) in the context of Sandal (footwear)

Sandals are an open type of footwear consisting of a sole held to the wearer's foot by straps that go over the instep and around the ankle. Sandals may also feature a heel of varying heights. While the distinction between sandals and other types of footwear can sometimes be unclear (as with huaraches—the woven leather footwear from Mexico—and peep-toe pumps), sandals are generally understood to leave most of the foot exposed.

People choose to wear sandals for several reasons, including comfort in warm weather, economic benefits (sandals typically require less material than closed shoes and are easier to manufacture), and as a fashion statement. Sandals are commonly worn in warmer climates or during warmer seasons to keep feet cool and dry. The open design reduces the risk of developing athlete's foot compared to enclosed shoes, and wearing sandals may be part of the treatment regimen for such infections.

A shoe is an item of footwear intended to protect and comfort the human foot. Though the human foot can adapt to varied terrains and climate conditions, it is vulnerable, and shoes provide protection. Form was originally tied to function, but over time, shoes also became fashion items. Some shoes are worn as safety equipment, such as steel-toe boots, which are required footwear at industrial worksites.

Additionally, shoes have often evolved into many different designs; high heels, for instance, are most commonly worn by women during fancy occasions. Contemporary footwear varies vastly in style, complexity and cost. Basic sandals may consist of only a thin sole and simple strap and be sold for a low cost. High fashion shoes made by famous designers may be made of expensive materials, use complex construction and sell for large sums of money. Some shoes are designed for specific purposes, such as boots designed specifically for mountaineering or skiing, while others have more generalized usage such as sneakers which have transformed from a special purpose sport shoe into a general use shoe.

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).

A climbing shoe is a specialized type of footwear designed for rock climbing. Typical climbing shoes have a tight fit, an asymmetrical downturn, and a sticky rubber sole with an extended rubber rand to the heel and the toe. Different types of shoes can be better suited for different levels of technique and routes.

The Juti or Jutti is a type of footwear common in North India, Pakistan, and neighboring regions. They are traditionally made up of leather and with extensive embroidery, in real gold and silver thread as inspired by royalty in the subcontinent over 400 years ago.

Juttis are sometimes made with rubber soles in the present day. Today Amritsar and Patiala ("tilla jutti") are important trade centers for handcrafted juttis, from where they are exported all over the world to Punjabi diaspora. Closely related to khussa, juttis have evolved into several localized design variations, even depending upon the shoemaker. However by large, they have no left or right distinction, and over time take the shape of the foot. They usually have flat sole, and are similar in design for both women and men, except for men they have a sharp extended tip, nokh curved upwards like traditional moustaches, and are also called khussa, and some women’s jutis are backless.

Saint Nicholas Day, also called the Feast of Saint Nicholas, observed on 6 December (or on its eve on 5 December) in Western Christian countries, and on 19 December in Eastern Christian countries using the old church Calendar, is the feast day of Saint Nicholas of Myra; it falls within the season of Advent. It is celebrated as a Christian festival with particular regard to Saint Nicholas' reputation as a bringer of gifts, as well as through the attendance of church services.

In the European countries of Germany and Poland, boys have traditionally dressed as bishops and begged alms for the poor. In the Portuguese city of Guimarães, the Nicolinas, a series of festivities in honor of Saint Nicholas, happen every year. In Poland and Ukraine children wait for St. Nicholas to come and to put a present under their pillows provided that the children were good during the year. Children who behaved badly may expect to find a twig or a piece of coal under their pillows. In the Netherlands and Belgium children put out a shoe filled with hay and a carrot for Saint Nicholas' horse. On Saint Nicholas Day, gifts are tagged with personal humorous rhymes written by the sender. In the United States, one custom associated with Saint Nicholas Day is children leaving their stockings hung up to be filled with mini gifts or leaving their shoes in the foyer on Saint Nicholas Eve in hope that Saint Nicholas will place some coins on the soles.

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.
