What Are The Restrictions On Soling Materials For Army Boots? A Guide To Ar 670-1 Compliance

For Army boots, soling material restrictions are straightforward: the sole cannot be more than 2 inches high and is prohibited from extending up the back of the heel or over the front of the toe. The regulations for the upper portion of the boot, which must be made of all leather or a combination of leather and non-mesh fabric, are equally important for compliance.

While the sole has specific height and shape restrictions, the true focus of Army regulations is on the overall durability and function of the boot. This is primarily dictated by the materials used in the upper construction.

Deconstructing the Sole Regulations

The rules governing the sole of an Army boot are designed to ensure a stable, traditional, and functional platform suitable for a wide range of duties.

The 2-Inch Height Rule

The sole's height, measured from the bottom of the outsole to the footbed, must not exceed 2 inches. This prevents overly thick or "platform" style soles that could hinder stability or create a non-uniform appearance.

The "No Extension" Rule

Soling material is not permitted to wrap up the back of the heel or extend over the top of the toe. This restriction disallows many commercial or athletic-style designs, ensuring a classic boot profile built for durability rather than specialized activities like running or climbing.

Beyond the Sole: Why Upper Materials Are Critical

While the sole has clear dimensional rules, the material composition of the boot's upper is where the standards for durability and performance are truly defined.

The Mandate for Leather & Non-Mesh Fabric

The boot's upper must be constructed entirely of leather or from a combination of leather and a non-mesh fabric. This requirement explicitly forbids the use of mesh panels common in athletic or running shoes, prioritizing ruggedness and protection over maximum breathability.

Common Compliant Leather Types

Full-grain leather, including "flesh-out" leather (which is essentially a rough-out suede), is the standard. It is chosen for its exceptional durability, abrasion resistance, and natural water resistance.

Approved Non-Mesh Fabrics

When fabric is used in combination with leather, it is typically a heavy-duty material like nylon or a nylon-cotton blend. These fabrics are used to reduce weight and increase flexibility without compromising the boot's structural integrity.

Understanding the Trade-offs

Choosing a compliant boot involves balancing durability, weight, and comfort. The material construction dictates these factors.

All-Leather Uppers

Boots made entirely of full-grain leather offer the highest level of durability and protection. They are more water-resistant but are also typically heavier and require a longer break-in period.

Leather and Fabric Uppers

Combining leather with durable nylon panels creates a lighter boot that is often more comfortable out of the box and requires less break-in time. The trade-off is potentially reduced durability in the fabric sections compared to an all-leather design.

Suede (Flesh-Out) Leather

This material provides excellent flexibility and comfort from the first wear. However, it is more susceptible to staining and can absorb water more readily than smooth-finished full-grain leather unless specifically treated.

Making the Right Choice for Your Goal

Selecting a compliant boot is about matching its material properties to your specific operational needs.

If your primary focus is maximum durability and protection: Choose a boot with a full-grain, all-leather upper for its superior resistance to wear and the elements.
If your primary focus is lightweight comfort and a quick break-in: Look for a combination boot that uses flesh-out (suede) leather and durable nylon fabric panels.
If you operate in consistently wet environments: Ensure your choice includes an integrated waterproof membrane, regardless of the primary upper material.

By understanding these material principles, you can confidently select a boot that is not only compliant but perfectly suited to your mission.

Summary Table:

Regulation Aspect	Key Requirement	Purpose
Sole Height	Must not exceed 2 inches.	Ensures stability and a uniform appearance.
Sole Shape	Cannot wrap up the heel or over the toe.	Maintains a classic, durable boot profile.
Upper Material	All leather or leather/non-mesh fabric (e.g., nylon).	Prioritizes durability and protection over breathability.
Common Leather	Full-grain or "flesh-out" (suede) leather.	Provides exceptional abrasion and water resistance.
