How to Choose and Replace Sneaker Laces

Why replace your sneaker laces

Laces wear out faster than most people expect. Fraying, stretching, and broken aglets (the plastic or metal tips) are common signs that it is time to swap in a fresh pair. Old laces also lose their grip, which means they come undone more often and force you to tie them tighter, creating pressure points across the top of your foot.

Replacing laces is also one of the cheapest ways to change how a sneaker looks and fits. A new pair can make a worn pair look fresh, and switching to a different material or color can change the whole character of the shoe. If you have a sneaker that slips at the heel or feels loose through the midfoot, a different lacing pattern or a stiffer lace can help lock your foot in place without buying a new pair.

How to measure lace length

The most reliable method is to measure the old lace. Lay it flat, pull out any kinks, and measure from tip to tip. If the old lace is missing or you are using it as a spare, count the number of eyelet pairs on your sneaker. That count is the main factor that determines lace length.

Here is a practical length guide based on the number of eyelet pairs. These are common industry lengths, but individual sneakers vary depending on how wide the eyelet spacing is, so when in doubt, size up slightly. A slightly longer lace can be adjusted, but a too-short lace cannot. If you want a looser, more relaxed style, add a few inches.

Lace material options

The material of your laces affects durability, grip, stretch, and style. Cotton laces have a classic look and feel but absorb water and dirt, and they stretch out over time. They are a good choice for casual sneakers and leather shoes where you want a traditional appearance.

Polyester and nylon laces are more durable, resist moisture, and hold their shape better than cotton. They are the standard for athletic and running sneakers because they stay tight during activity. Waxed laces have a coating that makes them water-resistant and gives them a slightly stiff, clean look. They hold knots well and are popular on dress sneakers and leather styles.

Elastic laces are the choice for slip-on convenience. They let you step into your sneakers without tying, and they adapt to different foot volumes throughout the day. They work well for kids, older adults, or anyone who struggles with bending to tie laces. If you are considering them, read our guide to installing elastic laces.

Removing the old laces

Start by loosening the laces all the way down to the toe. Unthread each eyelet from top to bottom, and set the old laces aside if you plan to use them as a length reference. If the aglet is broken, pull the lace out from the inside of the shoe rather than forcing it through a tight eyelet.

While the laces are out, it is a good opportunity to clean the eyelets and the tongue area. Debris can collect around the eyelets and make threading harder. A quick wipe with a damp cloth removes dust and grit. If you have metal eyelets, check for rust or sharp edges that could damage the new laces; see our guide on metal eyelet corrosion.

Threading the new laces

Thread the new lace through the bottom pair of eyelets, from outside to inside, so that both ends come out on top of the tongue. Even out the two ends so they are equal in length before you start crisscrossing.

Cross the ends and feed each one through the next eyelet up, from inside to outside. Continue this pattern all the way to the top. Keep the tension even as you go so that the tongue sits centered and the crosses line up. When you reach the top pair, you can either tie the laces normally or use a heel-lock loop if you want extra security at the ankle. For a visual walkthrough of different patterns, see sneaker lacing techniques.

Lacing patterns that change the fit

The way you thread the laces changes how the sneaker holds your foot. The standard crisscross is fine for most people, but if you have a narrow heel or experience heel slip, a heel-lock pattern (also called a runner's loop) pulls the ankle collar snug against your Achilles. It uses the top two eyelets to create a loop that locks the lace.

If you have wide feet or a high instep, a straight-bar lacing pattern reduces pressure across the top of the foot because it removes the crosses that press down on the vamp. For people with sensitive pressure points, this can make a big difference in comfort. Learn more about lacing pressure points and how a lace-up vs velcro closure changes the fit.

Final tips for lace replacement

Buy laces that are slightly longer than you think you need. You can always trim the excess and re-tip the ends with an aglet, but you cannot add length. When trimming, use a lighter to seal the cut end of synthetic laces so they do not fray.

Keep a spare pair of laces for each sneaker you wear often. Cyclists, runners, and walkers know that a broken lace mid-activity is a problem. The lace fray tolerance guide explains how much damage is acceptable before replacement. And if you want to refresh the look completely, changing to a contrasting lace color is an easy way to make an old pair feel new again.

What to pick for your use

Questions

How do I know what length laces to buy?

Measure your old lace from tip to tip. If you do not have the old lace, count the eyelet pairs: 5 pairs takes about 45 inches, 6 pairs about 54 inches, and 7 or 8 pairs takes 63 inches or more. When in doubt, choose a slightly longer lace.

Can I use elastic laces on any sneaker?

Yes, elastic laces work on most lace-up sneakers. They are especially convenient for slip-on use, kids, or anyone who has difficulty tying laces. Just match the length to your eyelet count, and thread them in the same pattern.

Why do my laces keep coming undone?

Worn laces lose their grip and stretch out. Replacing them with a fresh pair, especially in a polyester or waxed material, often solves the problem. Tying a double knot or using a heel-lock pattern also helps keep laces secure during activity.

What is the best lace material for running sneakers?

Polyester and nylon are the best choices for running because they are durable, resist moisture, and hold their shape. Cotton laces stretch when wet and can lead to a loose fit during a run.

How often should I replace my sneaker laces?

Replace laces when you see fraying, when the aglets fall off, or when they no longer stay tied. For daily-wear sneakers, this is often every 6 to 12 months. Active athletes may need to replace them more frequently.
