At their core, combat boot laces are made from high-performance synthetic materials engineered for extreme durability and environmental resistance. The most common materials are nylon, polyester, and paracord, each chosen specifically to withstand the harsh conditions of military and tactical use.
The material used for a combat boot's laces is not a stylistic choice; it is a critical component of a larger system, selected for unwavering strength, resistance to the elements, and in some cases, life-saving utility.

The Core Materials of Combat Laces
The demands placed on combat boots require laces made from materials that will not fail. Natural fibers like cotton are completely unsuitable as they absorb water, rot, and snap easily under strain.
Nylon
Nylon is prized for its exceptional strength-to-weight ratio and abrasion resistance. It has a slight elasticity, which can help maintain a snug fit as you move, but it is engineered to prevent excessive stretching.
Polyester
Polyester is another common choice, known for being hydrophobic, meaning it naturally repels water. This prevents the laces from becoming waterlogged, heavy, or frozen. It also offers excellent resistance to UV degradation.
Paracord (550 Cord)
Paracord is a specialized type of nylon rope with a unique kernmantle construction (a core of smaller strands protected by a woven outer sheath). It is not just a lace but a survival tool, valued for its high tensile strength and the ability to be deconstructed for emergency use.
Why These Materials Are Essential
The selection of these synthetic fibers is a direct response to the operational environment. The goal is to create a lace that is essentially "fire and forget"—it works without fail so the user can focus on their mission.
Unwavering Durability
Combat boot laces are constantly subjected to friction from metal eyelets and abrasion from rocks, dirt, and debris. Nylon and polyester are chosen for their ability to withstand this constant wear without fraying or snapping.
Resistance to Environmental Factors
In the field, boots are exposed to water, mud, and extreme temperatures. These synthetic materials will not rot, grow mildew, or weaken when wet, ensuring reliability across all conditions.
Secure Knotting
The weave and texture of these laces are designed to create friction, which helps hold a tight knot securely. A boot that comes untied at a critical moment is a significant liability, and these materials are engineered to prevent that.
Understanding the Trade-offs
While all are excellent choices, there are minor differences to consider based on the specific application.
Nylon vs. Polyester
Nylon offers slightly better abrasion resistance and a minor degree of stretch for comfort. Polyester, on the other hand, has virtually no stretch and superior water resistance, ensuring the laces never get heavy or sag.
The Paracord Compromise
While its utility is unmatched, paracord is often thicker than standard-issue laces. This can make it difficult to thread through smaller eyelets and may require more effort to tie a knot that stays completely secure due to its rounder shape.
The Importance of Weave
Beyond the raw material, the construction of the weave (e.g., braided, flat) significantly impacts knot retention and durability. A tight, high-quality braid will always outperform a loosely woven alternative, regardless of the material.
Making the Right Choice for Your Goal
Selecting the correct lace material depends entirely on your primary intended use.
- If your primary focus is military-grade reliability: Choose a dedicated, high-quality braided nylon or polyester lace designed specifically for boots.
- If your primary focus is survival and emergency preparedness: Choose 550 paracord for its unparalleled dual-use functionality.
- If your primary focus is maximum water and weather resistance: Choose a polyester lace for its hydrophobic properties.
Ultimately, equipping your boots with the right laces is a simple but critical step in ensuring your gear will perform when it matters most.
Summary Table:
| Material | Key Properties | Best For |
|---|---|---|
| Nylon | Exceptional strength, abrasion resistance, slight elasticity | Military-grade reliability, all-terrain use |
| Polyester | Hydrophobic (repels water), UV resistant, minimal stretch | Maximum water/weather resistance, consistent performance |
| Paracord | Kernmantle construction, high tensile strength, survival utility | Emergency preparedness, dual-use functionality |
