The Best Work Boot Fit & Fastening System - Laces, zips or dials?

Written by Matthew Roberts | 04/02/25 22:34

If you're in charge of Health and safety for a team, or if you're buying safety footwear for yourself, deciding between lace-up, zip-sided or dial system work boots (such as the BOA® Fit System) can seem like a potentially complex process. Why pick one fit and fastening system over the other?

In this blog, we'll be explaining the benefits of each option, and we'll also highlight how these particular styles could give you optimum results based on you or your team's particular job role, work environment and workplace hazards.

You'll learn too that your decision should also be a case of spec over style - although fortunately, the safety boots you'll see in this piece all happen to be pretty stylish...  

Laces

Laces are the classic fastening method. And when we say classic, we mean it - they've been around for 230 years!

Pros: 

Adjustable Fit  

Laces give the wearer a snug fit, and as they run right the way up the tongue in work boots, they can be adjusted to be looser or tighter around areas of the foot and ankle to avoid painful areas, or to increase stability.  

Durability 

Laces are pretty tough, but if they break, they're inexpensive to replace. 

Versatility 

Lace-up safety footwear comes in a wide variety of styles such as shoes, trainers, hikers and hi-legs, which makes them suitable for various safety-critical environments including Construction sites and Manufacturing Plants to Waste and Recycling roles. 

Traditional Design  

Given the choice, many prefer the classic, rugged look of lace-up boots.

Things to consider:  

Time  

Compared to a dial system or zips, it takes more time to tie/untie laces, which can be frustrating if boots need to be removed or adjusted frequently.  

Loosening   

Over time, laces can loosen or become fully undone - especially if the wearer is moving a lot - which might require readjustment and retying throughout the day, and of course, untied laces are the ultimate tripping hazard.   

Potential snagging 

It's easy to assume that slips, trips and falls are mostly due to slipping or unexpected contact with objects, but the risk of snagging laces on machinery or hardware with protruding nails or screws is significant, and can lead to serious injury.

ZIPS

Pros:

Quick On/Off

Zip-sided boots are very easy to put on and take off, saving time at the start and end of a shift. This is especially helpful in jobs where boots need to be removed regularly.

Ease of use

Once the laces of a zip-sided style are tied and fastened to the desired tightness, you can keep the laces in position and use the zip for the quick and easy on and off.

Adjustability

You can still adjust the laces for a custom fit, but equally, the zip can be relied on for the daily convenience of the main on/off. In a sense, a lace up zip-side gives you the best of both worlds.

THINGS TO CONSIDER:

Durability

Zips - particularly if the boots aren't looked after properly - can sometimes get jammed, break, or wear out over time, especially in harsh environments. And once the zip breaks, repair can be costly or difficult, which often spells the end of the boot's life.

Fit Limitations

A zip might limit how tightly a pair of safety boots can be adjusted compared to a purely lace-up style, potentially making them less secure for people who are after a greater feeling of stability.

Water and Dirt

Some safety styles feature zips which can let in dirt, water, or mud if they are not waterproof, which can be an issue in wet or dirty work environments. Having said this, there are plenty of zip-sided boots that come with a waterproof covering. 

THE Dial FIT system

Work Boots with a dial and lace system such as the BOA® Fit System allow for quick adjustments for a precision fit. This allows the wearer to quickly and easily tighten or loosen boots to their exact preference, providing a consistently even fit.


Pros:

Fit

The BOA® Fit System - consisting of a dial, laces and guide - gives a micro-adjustable fit, which enables the wearer to find just the right amount of snugness, ensuring a glove-like fit for the foot, as well as stability, which in turn decreases the risk of trips and falls.

Quick On/Off  

Micro-adjustable systems are faster to put on and take off compared to boots with alternative fastening methods. On the BOA® Fit System for example, to release the laces quickly, all the wearer needs to do is tug the dial out and they loosen immediately.

Frequently asked question:

"Laces? I thought the micro-adjustable BOA® Fit System doesn't have laces?"

Well, footwear with the BOA® Fit System don't have traditional fabric laces, but BOA® still refer to the stainless steel wires that move through the guides and tighten the footwear as laces. See this innovative and efficient system for yourself below:

 

 

Low Maintenance  

Compared to fabric laces, there's a much smaller chance of a dial system breaking or becoming untied. Take the BOA® Fit System: the laces in this technology are designed to withstand loads up to ten times higher than required, and furthermore, BOA® dials can be opened and closed 5,500 times without losing their functionality—that’s the equivalent of taking your shoes on and off once a day for over 15 years! Take a look below:

 

Hands and hassle

In environments where boots need quick or frequent adjustments, this system can save time, and is better for those who have limited dexterity in their hands due to having arthritis or needing to wear protective gloves, because boots can be fastened, adjusted and removed with just a turn of a dial, rather than laces needing to be tied or zips needing to be located and gripped tightly. 

THINGS TO CONSIDER:

Repair implications 

Adjustable dials can be more complicated to repair than fabric laces.

Too even a fit?

While many wearers feel micro-adjustable fit systems offer the benefit of an even, uniform fit across the foot, some argue that zonal fastening (making a certain area of the boot tighter or missing out an eyelet to avoid a pain point) can help people with foot health issues or a unique foot shape, and this can best be achieved with lace up boots.

Cost  

Unsurprisingly, boots with a more innovative and sophisticated fit or fastening system tend to be more expensive, due to the technology and additional materials involved in the manufacturing process.
