Question: What is the difference between a slider shoe and a non sliding shoe's design?
About the article "Curling", section "Shoes".

Candidate passages:
Curling shoes are similar to ordinary athletic shoes except that they have dissimilar soles; the "slider shoe" is designed for the off foot (or sliding foot) and the "non-sliding shoe" for the hack foot.
The "slider shoe" is designed to slide and typically has a Teflon sole.
It is worn by the thrower during delivery from the hack and by sweepers or the skip to glide down the ice when sweeping or otherwise traveling down the sheet quickly.
Stainless steel was once common for slider soles, and "red brick" sliders with lateral blocks of PVC on the sole are also available.
Most shoes have a full-sole sliding surface, but some shoes have a sliding surface covering only the outline of the shoe and other enhancements with the full-sole slider.
Some shoes have small disc sliders covering the front and heel portions or only the front portion of the foot, which allow more flexibility in the sliding foot for curlers playing with tuck deliveries.
When a player is not throwing, the player's slider shoe can be temporarily rendered non-slippery by using a slip-on gripper.
Ordinary athletic shoes may be converted to sliders by using a step-on or slip-on Teflon slider or by applying electrical or gaffer tape directly to the sole or over a piece of cardboard.
This arrangement often suits casual or beginning players.
The "non-sliding shoe", or "hack foot shoe," is worn by the thrower on the hack foot during delivery and is designed to grip.
It may have a normal athletic shoe sole or a special layer of rubbery material applied to the sole of a thickness to match the sliding shoe.
The toe of the hack foot shoe may also have a rubberised coating on the top surface or a flap that hangs over the toe to reduce wear on the top of the shoe as it drags on the ice behind the thrower.
In July 2008, Questlove collaborated with Nike to design the Questlove x Nike 1World Air Force 1 shoe.
The shoe's color is a blend of burgundy leather and red canvas with neon green elephant print—it has red shoelaces, a lasered silhouette of Questlove on the back of the shoe which is also featured on the left tongue, and a gold colored Nike swoosh logo.
Questlove stated that these shoes are "an extension of personality" as he sought to make "a very loud statement, a sneaker that sort of has 12 exclamation points behind it.
"Questlove's second Nike Questo sneaker was released in mid-February 2011.
The shoe is a combination of four popular Nike designs: the exterior body of the Dunk (footwear), the interior cushion of the Nike Delta Force, the sole of the Air Force 1 (shoe), and the swoosh from the Nike Blazers.
The shoe's color is a premium leather red with a white swoosh, and the velcro front's six clear buttons are designed to look like a dress shirt.
A lasered silhouette of Questlove is also featured on the tongue of the shoe.
Limited edition non-velcro versions were also released that are black-colored with a yellow and white sole. 
The shoe, usually made with a white leather upper and laces, has a simple design.
Unlike most Adidas shoes, it does not have the external three stripes.
Instead there are three rows of perforations (or punched ventilation holes) on both sides of each shoe's leather upper in the same pattern that should symbolize the three ordinary stripes.
There is sometimes a sketched picture of Stan Smith on the tongue of the shoe.
In some sense, the Adidas branding is minimal on the shoe.
The design and form of the shoe has basically stayed the same since it was introduced, but several new versions and colorways have appeared during the years. 
A "slider" or slide phone is composed of usually two, but sometimes more, sections that slide past each other on rails.
Most slider phones have a display segment which houses the speaker used for calls and for the phone's screen, while another segment contains the keypad or keyboard and slides out for use.
The goal of a sliding form factor is to allow the operator to take advantage of full physical keyboards or keypads, without sacrificing portability, by "retracting" them into the phone when they are not in use.
Many different companies have developed phones that slide.
Samsung has the Corby and BlackBerry has the Torch.
The Siemens SL10 was one of the first sliding mobile phones in 1999.
Some phones have an automatic slider built in that deploys the keypad.
Many phones "pop out" their keypad segments as soon as the user begins to slide the phone apart.
Unique models are the 2-way slider where sliding up or down provides distinct functions; such as the Nokia N85 or Nokia N95.
A version of the slider form factor, the side slider or QWERTY slider, uses vertical access of the keyboard on the bottom segment.
The side slider form factor is primarily used to facilitate faster access to the keyboard with both thumbs.
The Danger Hiptop, Sony Mylo and HTC Touch Pro are three primary examples.
Sliders supplanted the flip form, since they allowed manufacturers to pack more keypad buttons and features (especially the side slider or QWERTY slider, particularly suited to smartphones of the time) into the same form factor, while touchscreen interfaces were still in their infancy.
By the late-2000s, "slider" designs reached the peak of their popularity and declined afterward, being replaced slate/touchscreen bars form factors with well-developed touch interfaces.
The slate/touchscreen design does not having any fragile moving parts and is generally more compact than a slider form factor. 
In most pointe shoes, the sole is constructed from a single piece of leather that is attached to the shoe with adhesive and reinforced by stitching along its edges.
The sole overlaps and secures the unfinished edges of the shoe's exterior fabric.
Pointe shoes may be manufactured with either scraped soles, which provide superior traction, or buffed soles, which have a smoother surface for reduced traction.
Aesthetic appearance is of paramount importance for modern pointe shoes.
To achieve an elegant appearance, the shoe's more decorative outer fabric is prominently featured, covering the maximum possible area of the shoe's visible surfaces.
To this end, the sole is made of thin material to give it a minimal profile, and a margin of satin is artfully pleated around it so that the sole covers only part of the bottom of the shoe.
