Shoelaces help keep your shoes on. 

Shoelaces are strings used to hold shoes on your feet. 

Laces come in many styles. Some are round and some are flat. Flat laces often stay tied better. Some laces are elastic. These are great for kids or athletes. You can just slip them on. People also lace shoes in different ways. Straight-bar lacing looks neat on formal shoes. 
Shoelaces are small but important tools used to secure footwear like shoes and boots. 

There are many different ways to make and use laces. Traditional laces were made from things like leather, cotton, or hemp. Modern laces often use synthetic fibers that are smooth and resist rotting from water. Some laces are even made of flame-resistant material for firefighters. You might see flat laces, which are easier to hold and stay tied. 
People have been using laces for a very long time. It is hard to know exactly when they started because old shoes rot away. We found a leather shoe from around 3500 BC with leather laces.
Keeping a knot tight is a special skill. When you tie a knot, the lace gets squashed or "crimped." This makes the lace narrower inside the knot so it cannot slide out. Most people use a simple bow knot to finish. If you tie the loops the wrong way, you might make a "granny knot." 

Laces can also be a way to show your own style. You can add colorful laces or decorative charms called deubré. 
Shoelaces, also known as shoestrings or bootlaces, are essential systems used to secure footwear. 

The mechanics of a secure lace rely on friction and compression. When a knot is tied, the lace is crimped, or squashed. This makes the lace narrower inside the knot than on the loose ends. Because the lace cannot make itself smaller, it cannot slide through the knot. The shape of the lace also affects this process. Flat laces provide more surface area for friction than round laces. 
Laces vary significantly in their construction and material properties. Traditional laces were made from leather, cotton, jute, or hemp. Modern laces often use synthetic fibers like polyester. These synthetic materials are smoother and resist rotting from moisture. However, they can be more slippery and prone to coming undone. To fix this, manufacturers may use coatings like wax or silicone to increase friction. Specialized fibers, such as flame-resistant Nomex, are even used for firefighter safety boots.
There are many ways to lace a shoe depending on the style. Straight-bar lacing creates horizontal, parallel lines on the exterior. This method is common for formal Oxford shoes to maintain a neat appearance.
Knots are the primary way to finish the lacing process. Most people use a common bow knot, which consists of two half-knots. If the knots are tied correctly, they form a square or reef knot. If the loops lie across the shoe, it is likely a square knot. However, if the loops lie along the shoe from heel to toe, it is likely a "granny knot." 

History shows that lacing has been used for thousands of years. Archaeological evidence includes the Areni-1 shoe from around 3500 BC, which used leather laces. Around 3300 BC, Ötzi the Iceman used laces made of lime bark string. By the 12th century, medieval footwear used hooks and knots to stay on. In 1790, Harvey Kennedy popularized the use of aglets in the UK. These metal or hard tips changed how people handled their footwear daily.
Laces also serve as a medium for personal expression and specialized utility. People use colorful dyes, permanent markers, or decorative charms called deubré to customize their look.
