The Lock Laces Advantage



The lock incorporates a sliding, spring-activated device. The locks are made from a strong, durable nylon and use a high-tension alloy spring that won’t rust or corrode. The locking device holds the laces in place so they stay secure and maintain the same constant tension on the foot, never loosening.


The innovative curved tips of the laces allow the wearer to lace shoes easily through the eyelet configurations in athletic shoes. The laces are made with multi-banded strands of elastic (the same elastic used for bungee cords) that won’t break or dry rot. The elastic laces give you greater flexibility with a tighter, more comfortable fit than cotton or nylon shoelaces.

The LOCK LACES Advantage

With LOCK LACES™ patented "elastic shoelace and fastening system," you have a product that is high tech with low maintenance. Worry-free LOCK LACES™ provide a better fit for improved performance.

Running Shoe Lacing Techniques

Many people underestimate the power of proper lacing. Instead of overtightening your shoes, try these simple techniques to ensure a secure fit. "Forefoot nerves are superficial and easily damaged by shoe laces that are tied too tight, "says Dr. Hecker. Use the extra eyelet at the top of the shoe to "lock" the laces in place.

Running Shoes Guide


If you experience heel slippage, lock lacing will help. Lace the shoe normally until the lace ends emerge from the second set of eyelets. Then feed the laces up each side and into the top eyelet towards the foot. Now cross laces over, and feed each under the vertical section of the other side. Pull and tie normally.


This method of lacing is great to ensure a secure fit for any running shoe. After lacing, put each lace end back through the last hole to create a small loop on the top side of the shoe. Thread each loose end through the loop on the opposite side, pull and tie to create a tight closure.


If you have a high instep, this lacing technique might make you more comfortable. Start with normal lacing at the bottom, then feed the laces up each side of the shoe and cease to criss-cross. Once at the top, continue the criss-cross technique and tie for a secure closure.


If you have a wide forefoot, consider buying shoes especially designed for this issue. You can also try this simple technique. Begin by feeding the laces up each side of the shoe and only use the criss-crossing technique towards the top. Tie for a secure closure.

A Scientific Look at How to Lace Your Running Shoes to Reduce Injury and Increase Comfort

Most biomechanics and physiology researchers focus their efforts on big topics like injury, performance, and health. These research papers are usually centered on fundamental issues like impact, pronation, and oxygen consumption.

But, fortunately for us, a few researchers take the time to investigate some of the lesser but still important topics.

For example, a while back, we looked at some scientific studies on chafing and blistering in runners—a nontrivial topic for many of us!

Today, we’ll look at another of those “little details”: how should you lace your running shoes?

The science of how you should lace your shoes

One particular research group, headed by Marco Hagen at the University of Duisberg in Germany, has published several papers on just that question. The first of these papers, published in 2008, looked at the biomechanics of twenty distance runners moving at 8:00 mile pace on a treadmill under a variety of different lacing conditions. Data on impact force, pronation, and the pressure under the sole of the foot were collected.

All runners wore the same shoe, a Nike Air Pegasus, but laced several different ways. As do most running shoes, the Pegasus has six eyelets on each side, plus a seventh at the top which is slightly offset from the rest. The first three lacing conditions involved tying the shoes (with the normal 6-eyelet cross lacing) with different tightnesses, “weak,” “normal,” and “tight,” as perceived by the subjects in the study. After that, the researchers tested some additional lacing patterns, including an incredibly lose two-eyelet lacing (using only the first and second eyelets, a three-eyelet lacing (using the first, third, and fifth), and a seven-eyelet lacing using a “heel lock” loop on the final shoe eyelet, as depicted below.

Normal lacing and seven-eyelet heel lock lacing

The results showed that shoes tied tightly reduce pronation velocity and, more importantly, reduced impact loading rates. As you might have guessed, the looser and less comprehensive lacings using only two or three eyelets resulted in increased impact loading rates and pronation velocities. Pronation has not been reliably tied to injury rates, but impact loading rates have, so a reduction in loading rate by simply tightening your shoes is noteworthy.

A tight lacing also reduced localized pressure on the outside of the foot, likely by pulling the heel deeper into the shoe’s insole. However, there was a downside—the runners consistently reported the tight-laced condition as being one of the least comfortable. However, Hagen et al. found that the seven-eyelet “heel lock” lacing at a normal tightness was just as effective at reducing impact loading rates, pronation velocity, and plantar foot pressure as the standard six-eyelet lacing tied tightly.

In a later study, Hagen and his colleagues conducted a similar experiment, however, this time they added a measurement of the pressure on the top of the foot. This is an important step forward, as increasing the tightness of your laces increases pressure over the top of the foot, including the navicular bone and the extensor tendons that cross the ankle. While these areas are not injured very often, injuries to the navicular and extensor tendons can be very bothersome.

Using a similar experimental procedure, Hagen et al. tested fourteen male runners using only the normal six-eyelet lacing, the seven-eyelet heel lock, and a variant of the heel lock in which the sixth eyelet is skipped. The results showed that the two lacings that utilize the seventh eyelet result in lower pressures on the top of the foot without sacrificing any significant amount of stability in the foot’s contact with the insole of the shoe.

The special heel lock which skips the sixth eyelet (pictured below) was particularly effective at reducing pressure on the top of the foot.

One lacing style I was disappointed that Hagen did not investigate is “ladder lacing” (sometimes called “Lydiard lacing” after Arthur Lydiard, who advocated its use in some of his books in the ‘60s and ‘70s).

Ladder lacing is a technique which (purportedly) reduces pressure on the top of the foot by not allowing the laces to cross over the middle of the metatarsals. I would be interested to see whether this preserves shoe stability while reducing pressure on the top of the foot.

Additionally, many shoes today come with straps instead of eyelet holes. It’s unclear whether these provide any additional stability or advantages compared with regular eyelets. As always, there’s more research to be done!

Final notes

  • For the average runner, Hagen’s work highlights the importance of lacing up your shoes snugly. Most runners would probably be well-served by using a heel-lock lacing to increase the stability of their shoe and decrease their impact loading rates.
  • If you are prone to injury on the top of your foot, or if you find tight or high lacing uncomfortable, try using the special heel lock, as it has all the benefits of the regular heel lock or tight normal lacing, but with less pressure on the top of the foot. And lastly, don’t forget to double-knot your shoes!
