How to Keep Shoelaces From Coming Untied
If your shoelaces keep coming untied, the problem may be the knot, the lace material, or the amount of movement inside the shoe. Using a more secure knot, adjusting lace tension, or switching to laces with better grip can often solve the problem without replacing your shoes.
For athletes, secure laces are especially important. Running, jumping, and quick changes of direction can gradually loosen a poorly tied knot, leaving the shoe less secure and forcing you to stop and retie it.
Quick takeaway: Start by checking your knot. A secure square knot, double knot, or surgeon’s knot is usually the simplest solution. If the problem continues, consider a different lace material or a locking lace system.
Why Do Shoelaces Become Untied?
Shoelaces usually come untied because of a combination of knot technique, lace material, fit, and movement. During activities such as running, tennis, basketball, or gym workouts, repeated motion can gradually loosen a knot that wasn’t very secure to begin with.
The Knot May Be the Problem
A poorly formed knot can loosen much more easily during movement. One common problem is tying a granny knot instead of a balanced square knot. If your bow frequently twists vertically or comes undone, changing how you form the knot may help.
Adding a second knot can provide extra security, but we’ll cover the different tying methods later in this guide.
Some Lace Materials Slip More Easily
Smooth or slick shoelaces may have less friction than more textured laces, making it easier for a knot to loosen.
Age matters too. Worn, stretched, or damaged laces may not hold as securely as they once did.
Shoe Fit and Lace Tension Matter
Shoelaces need enough tension to hold the shoe securely without making it uncomfortably tight.
If the shoe is too loose or the laces aren’t tensioned evenly, movement inside the shoe can put additional stress on the lacing system. That repeated movement can gradually loosen the knot.
Athletic Movement Can Accelerate Loosening
Running, jumping, stopping, and changing direction repeatedly put the shoe and laces in motion. That’s one reason a knot that seems perfectly secure while you’re standing still may begin to loosen during a workout or sport.
The more movement involved, the more important it becomes to use a knot and lace setup that stays secure during activity.
What Types of Shoelaces Stay Tied Best?
Â
The material, shape, thickness, and condition of your shoelaces can all affect how securely they stay tied. If you’ve tried changing your knot but your laces still regularly loosen, the laces themselves may be contributing to the problem.
Textured vs Smooth Laces
Laces with a more textured surface can create additional friction within the knot, while very smooth or slick laces may be more prone to slipping.
Cotton laces are one option because their textured surface can provide good grip when tied. Waxed laces also add friction and stiffness, which can help a knot hold securely.
The exact material isn’t the only consideration, though. Construction, thickness, and the condition of the lace also matter.
Round vs Flat Laces
Both round and flat shoelaces can work well, so shape alone shouldn’t determine your choice.
What’s more important is whether the lace forms a secure knot in your particular shoe. Very thin or slick laces may be more likely to move within the knot, while a lace with enough texture and surface contact can be easier to keep secure.
Replace Worn or Damaged Laces
Inspect your laces if they repeatedly come undone. Fraying, stretching, damaged aglets, or worn areas can be signs that replacement makes more sense than continually changing how you tie them.
New laces are an inexpensive fix compared with replacing an otherwise perfectly usable pair of shoes.
Elastic and Locking Laces
Elastic, bungee, and locking laces offer an alternative for people who don’t want to rely on a traditional bow.
These systems can be especially convenient for athletic activities where quick adjustments or easy on-and-off are useful. The best option depends on the shoe, activity, and how much adjustability you prefer.

What Are the Best Ways to Keep Shoelaces From Coming Untied?
If your shoelaces regularly loosen during walking, running, or sports, changing how you tie them is usually the best place to start. You don’t necessarily need a complicated lacing pattern—a small change to the knot may be enough.
1. Square Knot
A secure bow starts with a balanced base knot. A square knot is formed by crossing the laces in opposite directions during the two stages of tying.
If your finished bow tends to sit sideways across the shoe, that’s generally what you want. If it repeatedly twists so the loops point more toward the toe and heel, your tying sequence may be producing a less stable granny knot.
Before trying anything more complicated, correcting the basic knot is a good first step.
2. Double Knot
A double knot is one of the simplest ways to add extra security. Tie your shoes normally, then tie the finished loops together one additional time.
This can be useful for running, court sports, gym workouts, or other activities where repeated movement tends to loosen your normal bow.
The tradeoff is convenience: a tight double knot can be more difficult to untie when you’re finished.
3. Surgeon’s Knot
A surgeon’s knot adds an extra wrap to increase friction and help the knot resist loosening.
It can be useful when your laces tend to slip even though the shoe otherwise fits properly. It also gives you additional security without necessarily requiring a very tight double knot.
4. Heel Lock (Runner’s Loop)
A heel lock, sometimes called a runner’s loop, uses the upper eyelets to create loops that help secure the heel more firmly inside the shoe.
This technique is primarily used to adjust fit and reduce heel movement rather than simply to prevent the final bow from untying. However, a more secure fit can help keep the overall lacing system stable during movement.
5. Lock Lacing
Lock-lacing techniques use the eyelets and lace path to help maintain tension in particular areas of the shoe.
This can be useful when you want a more secure fit during running or sports involving repeated changes of direction. Just remember that tighter isn’t always better—the shoe should feel secure without creating uncomfortable pressure.
What About the Ian Knot?
The Ian Knot is a fast method of tying a standard shoelace bow. It can be useful if you want a quick, efficient tying technique, but you don’t need to learn a specialized knot simply to keep your shoes secure.
For most people, correcting an unstable basic knot or using a double or surgeon’s knot is the easier place to start.
Which Shoelace Tying Method Should You Try?
The best method depends on why your laces are coming loose. This quick comparison can help you decide where to start.
| Method | Best For | Main Advantage |
|---|---|---|
| Square Knot | Laces that regularly loosen during everyday wear | Corrects an unstable basic knot |
| Double Knot | Running, court sports, and workouts | Simple way to add extra security |
| Surgeon’s Knot | Laces that tend to slip within the knot | Adds friction to help resist loosening |
| Heel Lock / Runner’s Loop | Heel movement inside the shoe | Helps create a more secure heel fit |
| Lock Lacing | Maintaining lace tension during athletic movement | Helps secure specific areas of the shoe |
| Ian Knot | People who want a faster tying technique | Quick and efficient once learned |
Frequently Asked Questions About Shoelaces Coming Untied
Why do my shoelaces keep coming untied?
Shoelaces can repeatedly come untied because of the knot, lace material, uneven tension, shoe fit, or movement during activity. A poorly formed knot or smooth, slippery laces can make the problem more noticeable.
What is the best knot to stop shoelaces from coming untied?
Start with a properly formed square knot. If you need additional security for running, sports, or workouts, a double knot or surgeon’s knot can add extra resistance to loosening.
Why does my shoelace bow turn sideways or vertically?
A bow that repeatedly twists so the loops point toward the toe and heel may indicate that you’re forming an unbalanced knot. Changing the direction of one stage of your normal tying sequence can help create a more stable square knot.
Are flat or round shoelaces better at staying tied?
Neither shape is automatically better. Lace material, texture, thickness, condition, and the knot itself can all affect how securely the laces stay tied. Very smooth or thin laces may be more prone to slipping.
Does double-knotting shoelaces keep them from coming undone?
A double knot can add extra security by tying the finished loops together a second time. It’s a simple option for running, court sports, workouts, and other activities where repeated movement tends to loosen a standard bow.
Should I replace my shoelaces if they keep coming untied?
Not necessarily. Try correcting your knot first. If the laces are worn, stretched, frayed, damaged, or particularly slippery, replacing them with a more suitable pair may help them stay secure.

Final Thoughts
If your shoelaces keep coming untied, you probably don’t need to replace your shoes. Start with the simplest solution: check how you’re tying them.
A properly formed square knot may solve the problem on its own. For athletic activities, a double knot or surgeon’s knot can provide additional security, while heel-lock or lock-lacing techniques can help when shoe fit and lace tension are part of the problem.
If changing your tying technique doesn’t work, take a closer look at the laces themselves. Worn or slippery laces can be inexpensive to replace, and sometimes that small change is all that’s needed.
