What is a requirement for structural firefighting boots?

A requirement for structural firefighting boots is a slip-resistant sole. This is essential because firefighters often work in hazardous environments where slipping can lead to serious injuries, especially on wet, uneven, or debris-laden surfaces. The slip-resistant sole enhances traction, allowing firefighters to maintain stability while maneuvering through dangerous situations during fire suppression and rescue operations.

While features like a pull-on design, rubber outer layer, and zipper closure may offer advantages in convenience, waterproofing, and ease of wear, they do not directly address the critical safety concern of traction, which is vital for a firefighter's performance and safety during operations.
