Inline skate is the kind of skates used for inline skating. Unlike quad skates, which have two front wheels and two rear wheels, the inline shoes usually have two to five wheels arranged in a row. Some, especially for recreation, have a rubber "stop" or "brake" block that sticks behind one or sometimes both shoes so that the skater can slow or stop by leaning on the foot with the bridal skates.
The inline modern shoe style was developed as a substitute for ice skates, to be used by the training of Russian athletes on solid ground for the Olympic track racing track. The magazine Life published an American skater photo of Eric Heiden, training for the 1980 Olympics, using such shoes on the Wisconsin road.
During the late 1980s and early 1990s, Rollerblade, Inc., a company founded by Scott and Brennan Olson in Minneapolis, Minnesota, is widely promoting inline skating through the Rollerblade registered trademark.

Histori
John Joseph Merlin experimented with a single device up to much that was used on the feet in 1760. Inline shoes, rollerboats designed to work like ice skates during warm weather periods, were created by Louis Legrange of France in 1849. Legrange designed shoes for opera in where a character appears on the ice. The shoes are problematic and do not work because the wearer can not spin or stop.
At a point between 1895 and 1899, the British engineering company D. Napier & Son made Ritter "road skates", which had two relatively large wheels, front and rear, on each skate.
The first US patent for modern in-line shoes, designed to behave like an ice runner with engined and bearing wheels, is provided with US patent number 2644692 in July 1953 Ernest Kahlert of Santa Ana, CA. They were briefly described in the April 1950 "Popular Mechanics" and again in the April 1954 edition of "Popular Science" in the section called "The New Idea of ​​the Inventor." Inline skates appeared in the 1962 Russian film Koroleva benzokolonki (Gas Station Queen) at 9m23s. In Canada in 1972, Mountain Dew attempted to sell Mettoy's "Skeeler" product, an inline skate developed for Russian hockey players and speed skater.
The first commercial inline skate available for this form of Rollerskating was in 1987 by Rollerblade. In 1996, Jason Lewis completed the first US solo crossing on an inline shoe, part of Expedition 360, a successful attempt to circumnavigate the globe using only human strength. On the way he was hit by a car in Colorado, broke his legs. After nine months, he completed a journey from Fort Lauderdale to San Francisco. In 2012, Kacie Fischer became the first woman, and the fastest man, for inline skates across the United States; He drove from California to Florida in 47 days.

Section
Skate consists of boot, used on foot. To boot mounted frame , which holds the wheel in place. Bearing allows the wheel to rotate freely around the shaft. Finally, rubber brakes usually sticks to the right foot frame.
There are different types of inline skates for different types of skating such as aggressive skating, speed skating, inline hockey, and inline artistic skating. They differ in boots, frames and wheels used.
Boot
For most skating, high boot is used, which provides more ankle support and is easier to glide, especially for beginners. Speed ​​skaters often use a carbon fiber boot that provides greater support with lower cuts allowing more flexion of the ankle. For recreational skating, softboats are used for greater convenience, but many other disciplines prefer harder boot, either to protect the leg against impact or for better skate control. Booting can also contain shock absorbing pads for convenience. Decreased skaters often use hot-printed boots with legs, with a layer of foam.
Most shoes aggressively use hard boot or hard boot/soft to increase support.
Frame
Recreational shoes commonly use frames made of high-quality polyurethane (plastic). Low-end department or skate frame toy stores can consist of other types of plastics. Frame speed skates are usually built from carbon fiber or aluminum extrusions (more expensive but more dense), magnesium, or even pressed aluminum, which are then folded into frames (cheaper but less sturdy).
The carbon fiber frames are expensive but generally more flexible, making travel more seamless at the expense of a worse power transfer between the legs and wheels. In general, the carbon fiber frame weighs about 160-180 grams. Recently, high-end carbon fiber frames with monocoque construction have been introduced. They offer the same level of rigidity as the aluminum frame weighs only about 130g. Aluminum can weigh 170-240 grams. The frame length ranges from 2 framed freestyle wheel wheels (used in aggressive skating) to about 230 mm for short-framed four-wheels (used in most inline designs), up to about 325 mm for the frame of a five-wheeled race.
Bearing
The ball bearings allow the wheels to rotate freely and smoothly. Bearings are usually rated on the ABEC scale, the size of the precision tolerances being produced, ranging from 1 (worst) to 9 (best) in odd numbers. The ABEC standard was originally intended for high-speed machines, not skating applications, and did not take into account the quality of steel used, which is critical for how long the bearings last. While higher rated bearings are generally better in overall quality, whether they automatically translate into more questionable speeds. At least since 2007, the Rollerblade brand has begun to use their own rating system. For example, the Rollerblades brand currently uses the SG1 to SG9 ranking system, while the TwinCam brand uses "ILQ" itself ( I n L ine Q ualified) the rating system and the Bones brand use their own "Skate Rated" rating system.
A common mistake made in buying bearings is that more spending translates to higher speeds. Generally, clean inline skate pads account for about 2% of the rolling resistance produced by the best urethane inline wheels, so there is very little chance of increasing speed by spending more money on bearings. Newer pads on the market have been offered that use ceramic ball bearings instead of steel, which are more expensive than traditional steel bearings but are made of tougher materials.
Two bearings are used per wheel. The bearings slip into openings that are printed onto each side of the wheel hub, and the flange formed into the wheel hub holds the distance between the correct pads. In addition there is a spacer shaft either machine into the shaft or that glide over the shaft (depending on the shaft system used). Because the outer racing of the contact bearings spacer wheel and the inner races of the spacer shaft contact bearings, it is imperative that the relationship between these two spacers is correct. If the wheel spacer is wider than the pivot spacer, the bearing will bind when the axle bolt (or bolt) is tightened.
Wheel
Wheel sizes vary depending on the skating style. Watch carefully that the age factor of the skater comes in. The adult wheel size will not be the same as the child:
- 44-72 mm for aggressive skating.
- 47-80 mm for hockey roller skating.
- 68-72 mm for inline artistic skating.
- 72-80 mm for freal slalom skating and skating slopes.
- 70-90 mm for urban skating.
- 72-100 mm for general recreational skating.
- 80-90mm for inline skating decreases.
- 100-125 mm for tri-skating, blading mushrooms, and speed skating.
- 125-150mm tires for off-road skating.
The current wheels are almost universally made of polyurethane (a kind of durable plastic). Most of the other plastics and rubbers are too fast to wear or have too much rolling resistance. In general, the bigger the wheel, the faster the skate. The larger wheels roll over the road imperfections smoothly so the skating is not too wavy. On top of that, an inline skater travels much less on big wheels. However, large wheels require more energy to start spinning. The smaller wheels allow for faster acceleration, maneuverability, and a lower center of gravity.
Wheel hardness is measured on a scale A (see Durometer) and usually ranges from 72A-93A (softer lower numbers, higher numbers more difficult). The harder wheels are not always faster but tend to be more durable; the soft wheel may have a better handle and is generally less affected by the road bumps. The harder wheels (which provide minimal elastic hysteresis absorption) keep the scrolling speed much better while the softer wheels (because they grasp the surface) accelerate more straight when walking. In the 1990s, rolling resistance wheels (CRR - rolling resistance coefficients) tended to be minimized by wheel hardness in the range of 78A durometers, with rolling resistance rising dramatically below 75A durometer and above 85A durometer. In early 2000, the urethane compound increased significantly, allowing skaters to use harder compounds to obtain better wheel life, and obtain the lowest rolling resistance in the 82A-84A durometer range.
Wheel profiles and thickness again vary by app. The Elliptic profile is considered to minimize friction for faster travel; However, they are meant to mimic the blade's properties of an ice knife. They help determine the inside, the middle and the outside. The Elliptic profile makes the wheels quite maneuverable when turning or crossing. A more rounded profile provides lower rolling resistance because of "stomach" or larger tires that increase resistance (or "rebound"); and this wheel is considered to have a better and more stable grip (less like an ice knife), but heavier than elliptical profiled wheels and often used in downhill racing (such as Hyper Downhill racing wheels) and in recreational skating. Another advantage of the round profile wheel is its longer wear life due to increased urethane quantities on the tires. To improve stability at high speeds, skates intended for skating down usually have five or six wheels, unlike recreational boots, which usually have four wheels. The advantage of more wheels having less rolling resistance has been largely negated by the 100-110mm diameter wheel with 4 wheel truck. The flat profile allows the wheel to be much more stabler than a rounded profile. This profile is almost exclusively used on aggressive skate wheels. On the flip-side, the square-to-edge shape that causes cornering becomes very difficult, seeing how the edges do not exist with a flat profile. In fact, the flat profile has only the middle edge preventing the skater from leaning.
The core materials, shapes and designs located on wheel wheels determine the wheel properties as well. In a classical point of view, wheels on older skate models (during the 1980s and early 1990s) lacked any core features at all. The core is the result of a gradual increase in inline skating technology. Above all, the wheel that has no core is susceptible to deformation. This deformation is a barrier to the skater's swing ability because in such cases it minimizes the skater's highest speed. The core is inserted to hold the polyurethane firmly in place. Despite the setbacks, the market still distributes special wheels without a core. The core design varies between open, full or semi open. 'Fingers' are elements that are visible on wheels that are essentially exposed which generally increase overall lightweight wheels. These are incorporated into wheel hubs for inline skates, fitness shoes, leisure shoes, some slalom shoes and inline/artistic skates. The main disadvantage of open cores is that their designs do not allow robustness so they are very likely to snap under too much pressure ie when jumping. Another exchange with an open core is the lower number of polyurethanes in the vicinity to compensate for the shorter finger-shaped meaning. The full core is completely solid, similar to a pipe cross section. This core design is mostly preferred among aggressive skaters who leap from higher-level filter wheels when landing. Of course, these nuclei (in addition to the extra polyurethane) tend to add weight to the wheels. Some do not even like the full core design because of its uncomfortable rigidity. The question still depends on whether the full core increases the power transfer. The semi-open cores are a hybrid between two previously mentioned cores seen on wheels for urban shoes, slalom skates and inline hockey boots. Small holes are usually incorporated into these cores to provide a semi-open design.
Brake heel or toe tips
The hard rubber brakes attached to the heel of the frame allow the skater to stop by lifting the skate fingers, forcing the brakes to the ground. Learning how to use heel brakes is very important for beginners, as this is the easiest way to stop in an emergency and to control the speed at the downhills.
The heel brakes can interfere with a useful technique called crossover change, in which a skater crosses one leg over the other to make a sharp turn without losing much speed; for this reason, most middle to upper users choose not to use heel brakes. Skater players in freestyle slalom and aggressive inline skating discipline do not use heel brakes, as they limit the skater's ability to perform the tricks effectively. Aggressive inline shoes and racing shoes generally do not have a heel brake, allowing extra speed and control.
Inline skaters do not have a heel brake can use a variety of other methods to stop, such as a T-stop where the skater moves one skate perpendicular to the other, making the form "T" to increase friction and reduce speed, or more advanced maneuvers stop hockey/the snowplow stops, where the skater quickly moves both skates perpendicular to the path of motion.
For artistic purposes of roller skating, inline skating shoes can also feature a "toe stop" that helps in skating glide.
Settings
Flat Settings
Flat settings are the most common settings used on inline shoes. Almost all non-aggressive inline shoes are sold with a flat wheel setup. Flat means that all wheels touch the ground at the same time when resting on flat ground. Flat arrangements are not the most maneuverable but what they lack in the maneuverability they get in speed. Flat arrangements tend to be the fastest setting, compared to settings like HiLo or anti-rocker. The presence of two wheels is increasing the point of contact with any surface. They also minimize the rate at which the loading load of the skater destroys the wheel. This minimizes the wheel footprint so as to minimize rolling resistance. Speed ​​skater and skater marathon usually use a flat setup. Aggressive shoes are sometimes sold with flat settings, but with a small space in the middle to grind.
It should be noted that having a flat setup is just one factor in a quick skate setup. Long frames, low resistance bearings, and good technique all contribute greatly to the speed of the skater.
Full 'crescent/banana' Rocker
Full rockers are used by skaters that support maneuvering ability while skating on flat ground. Freestyle skaters, freestyle slalom skaters, and artistic inline skaters tend to use this configuration. This arrangement is called "crescent" or "banana" because it is curved, and mimics the profile of a curved ice knife. On flat ground, this configuration will only have 1-2 wheels touching the ground at a time. This makes skate easier to change but lacks stability making it more difficult to balance. In addition, the full rocker is slower than a flat setup in terms of top speed
Flat arrangement is generally used to be a 'natural' rocker. This is because the front and rear wheels seem to accept most of the wear on the inline shoes.
Having a short frame (230mm-245mm) in combination with a full rocker is optimal for achieving the highest maneuverability while skating.
Front Rocker
The front rockers are often used by street skaters who want to combine full rocker ability to handle imperfections on the ground with a flat setup speed. Having a smaller wheel at the front pushes the front wheel to guide the remaining skates over land imperfections, rather than digging and climbing less experienced skaters. Maintaining a flat profile on the back allows the skater to transfer power through the back of the skate efficiently to maintain a good speed.
' Hi-Lo 'Hockey Setup
Some hockey boots and other shoes include the HiLo arrangement. HiLo setup resembles a flat setup where all 4 wheels touch the ground at the same time. Unlike flat mounting, however, different wheel sizes are used. The two front wheels will be smaller than the two rear wheels. This is possible because of the axle location on the frame itself. One example is the Bauer frame that has two wheels in front of the 76mm and two wheels behind the 80mm. Another example is the wheel arrangement of 74mm-76mm-78mm-80mm. This drastically changes the speed at which the inline hockey player is accelerated. Furthermore, by transferring the weight forward, the skater can run explosively from the toes and reduce the incidence of falling backwards. If hockey skates are used recreatively outside the arena, skaters will find the climbing slopes much easier than on flat settings.
' Settings TriDi 'Hi-Lo
Another variant of the setting where there are three wheel diameter. This should emphasize the same benefits as the HiLo system but with greater maneuverability due to the smaller front wheels. The configuration is 72mm, 76mm, 76mm, 80mm.
Hi-Lo Aggressive Settings
Some of the aggressive frame skates (especially Rollerblades Frame, Ground Control's Bullet Frame, and Oysi Frame) are designed so that there are two large outer wheels, and two small inner wheels, shaken so that everything touches the ground. This provides the benefit of flat settings, while providing more rollerblader space for working on block H between wheels.
Anti-rocker
Anti-rockers are the most popular setup for aggressive skaters. The anti-rocker wheel is a small hard wheel that replaces the two center wheels. The anti-rocker wheels hardly ever touch the ground except in cases where the terrain is uneven, like sliding over a hill. Anti rocker can be made of plastic, or high density polyurethane. Some use cushions so they can spin. Others do not use bearings so it is lighter. Anti-crystals themselves lock the block H into the ledge or rail skater grinds. Anti-rocker settings make harder maneuvers, slower overall speeds, rougher journeys and wider turning radius, but because of the extra space in the center, it makes the grinding object a lot easier than with flat settings.
Freestyle
Frame freestyle is another arrangement used by aggressive skaters. This setting has only two wheels - one in front and one on the back. Between the two wheels is a solid material area, resembling a large "H Block", used for grinding. Freestyle frames can be purchased, although removing the two inner wheels from a flat frame or anti-rocker technically makes it freestyle, but this will not be very durable due to the lack of solid milling materials.
Tri-rocker
Tri-rockers are used by some aggressive skaters. This is another method to make grinds easier. The frame with tri-rocker arrangement has only one wheel in the center, either in the position of the second wheel or in the position of the third wheel, depending on what kind of grinds the skater will do. The remaining shaft has an anti-rocker wheel, special grinding block, or just left empty.
The goal of tri-rocker arrangement is to provide good skater maneuverability and speed, as in flat settings. But because of the extra space, grinding is also slightly easier than flat settings.
