Shoelaces , also called shoestrings (English English) or bootlaces (English English), are systems normally used to secure shoes, boots , and other footwear Usually they consist of a pair of ropes or straps, one for each shoe, finished at both ends with rigid parts, known as aglets. Each shoelace usually passes through a series of holes, eyelets, loops or hooks on either side of the shoe. Loosening the straps may allow the shoe to be opened wide enough for legs to be inserted or removed. Tighten the rope and tie the edges to secure the foot inside the shoe.

Shoelace Construction
Traditional shoelaces are made of leather, cotton, hemp, hemp, or other materials used in making ropes. Modern shoelaces often incorporate a variety of synthetic fibers, which are generally more slippery and thus more vulnerable to detach than those made from traditional fibers. On the other hand, smooth synthetic shoelaces generally have a less rough appearance, suffer less wear than friction, and are less prone to rot than moisture. Special fibers such as refractory nomex are applied in safety shoes to firefighters.
There are also a variety of elastic shoelaces:
- The traditional "elastic" strap looks identical to the normal string, and can be easily tied and removed as usual. They may also come with a permanent clip so they can be tightened without being seen.
- The "Knotty" strap has a series of "fat" parts, which restrict movement through the rope hole. This can be used to adjust the tension throughout the lacing area. This rope can be tied or the end can be left off.
- The "Twirly" string is like a tight elastic helix, which can be pulled without the need for a knot.
The elastic strap makes the blow more comfortable, and allows the shoe to be removed and removed without binding or unbinding, making it a popular choice for children, the elderly and athletes.
The rigid part on each end of the shoelace, both of which keep the yarn from breaking down and also make it easier to hold the lace and feed through the rope hole, called aglet, also spelled aiglet.
Shoelaces with flat sections are generally easier to hold and stay tied safer than rounded sections due to increased surface area for friction. A very wide strap is often called a "fat strap". Leather shoelaces with square cross sections, which are very common on boat shoes, are notoriously susceptible to removable.
Shoelaces can be coated, either in the factory or with aftermarket products, to increase friction and help them stay tied.

Shoelaces that bind
When shoelaces are secured with knots, lace is wrinkled, or pinched. Especially this is what stops the lace off. In effect, the lace is narrower in the knot than at the loose end, and the loose end can not make itself smaller and sliding even though it is the knot. Generally, flat tubular lace will remain bonded more easily than round lace with a core because flat lace can be more creased inside a knot. However, most of the ropes have a round and have a cotton yarn core, especially shoelaces. In order for this to remain securely bonded, the core inside the lace should be soft and compressible. The secondary factor of the loose rope is the knot itself slipping. This is because of the lack of friction. The cotton rope has a rough surface and will make the knot more reliable than the polyester (the most common thread used in shoelaces). In addition, lace can be smooth or have a rough surface, which will also affect performance. The finishing process is available, including waxing and silicon care, which improves friction and stops skipping nodes. This is an important design factor in making hiking shoelaces.
General arc
Shoelaces are usually tied at the top of the shoe using a simple bow knot. In addition to securing shoes, this also requires a long shoelace that looks after tightening. The general arc consists of two half nodes tied one on top of the other, with a second half node looped to allow rapid release of the bond. If required, the knot can easily be loosened by pulling one or both of the loose ends.
When tying a half knot, a half-right-top-left node is followed by a half-left-right node (or vice versa) forming a square or reef node, a knot that is quite effective for the purpose of tying a shoelace. However, tying two successive right-to-left nodes (or two left-right-half-consecutive nodes) forms the famous grandmother's node, which is much less secure. Most people who use it will find themselves regularly shuffling their shoelaces.
If the loop is in the shoe (left to right), the vertices may be square nodes. If they lie along the shoe (heel to toe), the knot is probably the grandmother's knot.
More secure nodes
There are some safer alternatives to common shoelace bows, with names like Turquoise Turtle Shoelace Knot, or Shoemaker Knot , Knots of Better Rope Cords, Knots of Surgical Shoes, and Knots of Shoes owned by Ian, or the double slip node . One such node was patented in 1999 under the title "shoelaces". These are all variations of the same concept of the upper looping of the knot twice instead of once, resulting in a final arc with an almost identical appearance but with a rope wrapped twice around the center. This double-wrap holds the shoelace closer while still allowing to release the bond (slightly firmer) at the loose end.
Length
The exact shoelace length, fitted to the shoe, varies according to the type of clock strap used, as well as the type of lace. However, in rough references, the following guidelines can be used.
Shoe hitting
This is the process of running a shoelace through a hole, eyelet, loop, or hook to unite the sides of the shoe with many common lacing methods. Actually there are nearly two trillion ways to unify shoes with six pairs of fish eyes.
Common lacing methods
Straight-line binding
Straight-bar lacing looks horizontal and aligned when viewed from the outside. Formal shoes usually require a straight line to keep the look clean and tidy. This is especially true for shoes using closed lacing systems such as Oxfords, because crossover cross-section crosslinks prevent the sides of the shoes coming together in the middle.
Crosslinking
The most common lacing method, called cross-cross , is also one of the strongest and most efficient. However, they are provided for more casual footwear, such as sneakers and boots. Derbies can be straight-bar mixed or alternately laced.
Other lacing methods
Many shoe-binding methods have been developed with certain functional benefits, such as faster or easier to tighten or loosen, tie more tightly, more comfortably, use more lace or less lace, adjust suitability, prevent slippage, and special shoe type settings. One such method, patented in 2003 as a "double helix shoe lacing process", runs in a double helix pattern and produces less friction and is faster and easier to tighten and loosen. Another method, called "Instant Lace Up Rinlers", uses additional accessories for tightening and instant easing.
Many other lacing methods have been developed purely for appearance, often at the expense of functionality. One of the most popular decorative methods, checkered amber, is very difficult to tighten or loosen without damaging the pattern. Shoes with drum rope are usually treated as "slip-ons".
Most of these hitting methods are not suitable for formal wear.
History
It is equally difficult to determine the exact history of shoelaces like shoes. Footwear archaeological records are rare because shoes are generally made of easily deteriorated material. Areni-1 shoes, dated around 3500 BC, are simple leather "shoes" with "leather laces" that pass through a "fish-eye" slit cut into the skin. More elaborate shoes are worn by ÃÆ'â € "tzi Iceman, which lives around 3300 BC, tied to a" shoelace "made of leather strap.
As for the shoelaces in the sense that we know them in modern times, the London Museum has documented examples of medieval footwear dating from as far back as the 12th century, which clearly shows the rope passing through a series of hooks or holes in the front. or side of the shoe.
Myth
The popular myth suggests that Gurkhas, who fought for Britain, crawled on the ground, felt the ropes of the soldiers they encountered. British troops use straight windings or bars, while Japanese troops use a cross pattern. The cross-cross can mean the difference between life and death. The importance of binding is properly emphasized on British troops. Whether true or not, there are reports of Gurkha soldiers checking the shoes and rope of the soldiers they meet in the dark to find out whether they are friends or enemies.
Shoestring accessories
There are many accessories of shoelaces. There are hooks to help lace the shoe lace tightly. They are very useful for roller skates where tight strike is important. The shoelaces protect the shoelaces, especially in wrestling. The charm of decorative shoelaces, such as colored shoelaces. Some colored straps using expensive dyes, other colors that are more "personal", are drawn with permanent markers. Some dress codes (especially high school) will specifically exclude straps of color and charm. The lace locks tie the rope together, eliminating the need to bind. There is a shoelace label, sometimes called deubrà ©  ©, with two holes or a gap where the shoelace is passed. It is worn on the part of the shoelace closest to the toes, in other words the last lace, so the image or writing on the tag is visible (as seen on the right).
