Ice skates are metal blades attached underfoot and used to propel the bearer across a sheet of ice while ice skating.
The first ice skates were made from leg bones of horse, ox or deer, and were attached to feet with leather straps. These skates required a pole with a sharp metal spike that was used for pushing the skater forward, unlike modern bladed skates.
Ice skating is the self-propulsion and gliding of a person across a flat ice surface, using metal-bladed ice skates. People skate for various reasons, including recreation (fun), exercise, competitive sports, and commuting. Ice skating may be performed on naturally frozen bodies of water, such as ponds, lakes, canals, and rivers, and on human-made ice surfaces both indoors and outdoors.
Natural ice surfaces used by skaters can accommodate a variety of winter sports which generally require an enclosed area, but are also used by skaters who need ice tracks and trails for distance skating and speed skating. Man-made ice surfaces include ice rinks, ice hockey rinks, bandy fields, ice tracks required for the sport of ice cross downhill, and arenas.
Synthetic ice is a solid polymer material designed for skating using normal metal-bladed ice skates. Rinks are constructed by interlocking panels. Synthetic ice is sometimes called artificial ice, but that term is ambiguous, as it is also used to mean the mechanically frozen skating surface created by freezing water with refrigeration equipment.
Synthetic ice is marketed under brand names including Glice, Xtraice, PolyGlide Ice and Global Synthetic Ice.
Speed skating is a competitive form of ice skating in which the competitors race each other in travelling a certain distance on skates. Types of speed skating are long-track speed skating, short-track speed skating, and marathon speed skating. In the Olympic Games, long-track speed skating is usually referred to as just "speed skating", while short-track speed skating is known as "short track". The International Skating Union (ISU), the governing body of competitive ice sports, refers to long track as "speed skating" and short track as "short track skating". Long track speed skating takes place on a 400m ice track, while short track takes place on a 111m track.
An international federation was founded in 1892, the first for any winter sport. The sport enjoys large popularity in the Netherlands, Norway and South Korea. There are top international rinks in a number of other countries, including Canada, the United States, Germany, Italy, Japan, Russia, Kazakhstan, China, Belarus and Poland. A World Cup circuit is held with events in those countries plus two events in the Thialf ice hall in Heerenveen, Netherlands.
Sportswear or activewear is athletic clothing, including footwear, worn for sports activity or physical exercise. Sport-specific clothing is worn for most sports and physical exercise, for practical, comfort or safety reasons.
Typical sport-specific garments include tracksuits, shorts, football or basketball jerseys, t-shirts and polo shirts. Specialized garments include swimsuits (for swimming), wet suits (for diving or surfing), ski suits (for skiing) and leotards and tights (for gymnastics or aerobics). Sports footwear includes football boots (also referred to as cletes), trainers, riding boots, tennis shoes (or running shoes), or ice skates. Sportswear also includes sports bras for running, crop tops, or a bikini top. Sportswear is often worn as casual fashion clothing.
Inline skates are boots with wheels arranged in a single line from front to back, allowing one to move in an ice skate-like fashion. Inline skates are technically a type of roller skate, but most people associate the term roller skates with quad skates, another type of roller skate with a two-by-two wheel arrangement similar to a car. Quad skates were popularized in the late 19th and early 20th centuries. Inline skates became prominent in the late 1980s with the rise of Rollerblade, Inc., and peaked in the late 1990s. The registered trademark Rollerblade has since become a generic trademark: "rollerblading" is now a verb for skating with inline skates, or "rollerblades."
In the 21st century, inline skates come in many varieties, suitable for different types of inline skating activities and sports such as recreational skating, urban skating, roller hockey, street hockey, speed skating, slalom skating, aggressive skating, vert skating, and artistic inline skating. Inline skaters can be found at traditional roller rinks, street hockey rinks, skateparks, and on urban streets. In cities around the world, skaters organize urban group skates. Paris Friday Night Fever Skate (Randonnée du Vendredi Soir) is renowned for its large crowd size, as well as its iconic +10 mile urban routes. Wednesday Night Skate NYC is its equivalent in New York City, also run by volunteers, albeit smaller in size.
Roller skates are boots with wheels mounted to the bottom, allowing the user to travel on hard surfaces similarly to an ice skater on ice. The first roller skate was an inline skate design, effectively an ice skate with a line of wheels replacing the blade. In modern usage, the term typically refers to skates with two pairs of wheels on shared axles like those of skateboards (early versions of which were made using roller skate parts). Skates with this configuration are also known as "quad skates" or "quads" and, like skateboards, steer by tilting the skate to one side, which causes the axles to turn inward.
Figure skates are a type of ice skate used by figure skaters. The skates consist of a boot and a blade that is attached with screws to the sole of the boot. Inexpensive sets for recreational skaters are available, but most figure skaters purchase boots and blades separately and have the blades mounted by a professional skate technician.
