Setup and Initial Use
Upon receiving your Timberland PRO True Grit boots, inspect them for any shipping damage. These boots are designed for a pull-on fit, but proper initial setup ensures comfort and longevity.
First Fit and Break-in
- Initial Wear: Wear the boots with the type of socks you typically use for work. Ensure your heel is seated comfortably in the heel cup.
- BOA Fit System Adjustment: The BOA Fit System dial is located on the side of the boot. To tighten, push the dial in and turn it clockwise. This micro-adjusts the internal lacing for a secure and precise fit around your ankle and instep. To release, pull the dial outwards. This system allows for quick and easy adjustments throughout the day.
- Break-in Period: While Timberland PRO boots are designed for comfort out of the box, a short break-in period is recommended. Wear them for shorter durations initially, gradually increasing wear time. This allows the leather and sole to conform to your foot shape.

Operating and Usage Guidelines
These boots are built for demanding work environments, offering protection and comfort. Adhering to these guidelines will maximize their performance and your safety.
Safety Features
- Composite Safety Toe: Provides protection against impact and compression hazards. Ensure the boot fits correctly to allow adequate toe room without rubbing.
- Electrical Hazard Protection: Offers secondary protection against accidental contact with live electrical circuits. This protection is effective in dry conditions and should not be considered a primary protection against electric shock.
- Waterproof Membrane: Keeps your feet dry in wet conditions. While highly effective, avoid prolonged submersion beyond the boot's height.
Comfort and Performance
- Anti-Fatigue Technology: The integrated anti-fatigue footbed is designed to absorb shock and return energy, reducing foot fatigue during long hours of standing or walking.
- ExoSpine Technology: This external heel counter provides enhanced stability and prevents heel slippage, contributing to overall comfort and reducing friction.
- Traction: The PRO rubber outsole is designed for superior traction on various surfaces. Always exercise caution on slippery or uneven terrain.

Maintenance and Care
Proper maintenance will extend the life and performance of your Timberland PRO True Grit boots.
Cleaning Instructions
- Remove Loose Dirt: Use a soft brush or damp cloth to remove any loose dirt, mud, or debris from the leather and sole.
- Clean Leather: For the premium waterproof leather, use a leather cleaner specifically designed for work boots. Apply with a soft cloth, gently rubbing in circular motions. Wipe off excess cleaner.
- Clean Soles: Use a stiff brush and water to clean the rubber outsole, ensuring all debris is removed from the tread for optimal traction.
- Drying: Allow boots to air dry naturally at room temperature. Avoid direct heat sources (like radiators or direct sunlight) as this can damage the leather and adhesives. Stuffing the boots with newspaper can help absorb moisture and maintain shape.
- Conditioning: After cleaning and drying, apply a leather conditioner or waterproofing treatment suitable for waterproof work boots. This helps to keep the leather supple and maintain its water resistance.
BOA Fit System Care
- Keep the BOA dial and laces free from excessive dirt or debris. If needed, gently clean with a damp cloth.
- Do not attempt to disassemble the BOA system. If issues arise, refer to the troubleshooting section or contact customer support.
