Preserve Your Work Boots
Built for the Job. Maintained for Longevity.
Your work boots are your foundation on the job—protect them to ensure they last as long as you do. Follow these essential care tips to keep your boots tough, reliable, and ready for every challenge.
Storage: Protect Your Gear
- Dry and Safe: Store your boots in a cool, dry space away from direct sunlight to prevent cracking and fading caused by moisture or UV exposure.
- Let Them Rest: Rotate your boots regularly to allow time for proper drying and to maintain their structural integrity.
- Shape Matters: Use a sturdy shoe tree or stuff them with newspaper to preserve their shape without stretching the leather or material.
Cleaning: Combat the Dirt and Grime
- Daily Dirt Removal: After a hard day’s work, brush off dirt and debris with a stiff-bristle brush. For stuck-on grime, use a damp cloth to gently clean the surface.
- Deep Cleaning: If your boots encounter oil, chemicals, or mud, use a mild soap or work-boot cleaner to remove residue, then rinse and dry thoroughly.
Conditioning: Keep Them Tough and Supple
- Choose Wisely: Use work-boot-specific conditioners or oils that won’t damage the leather or waterproofing. Avoid products with alcohol or harsh chemicals.
- Even Application: Apply conditioner sparingly, working it evenly into the leather with a cloth or brush. This keeps the material hydrated and prevents cracking.
- Right Frequency: Condition your boots 3–4 times a year or whenever the leather starts to feel dry. Avoid over-conditioning, which can weaken the material.
Protection: Prepare for the Job Ahead
- Weatherproofing: Apply a water-repellent or weatherproofing product to shield your boots from moisture, mud, and snow.
- Reinforce Soles: Inspect your soles regularly and replace them when worn to ensure safety and stability on the job site.
