Given your previous mention of "Tiger Racing" as a brand for off-road boots, it's highly likely that "TR" stands for Tiger Racing. The "G3" would then denote a specific model or generation of their on-road boots.

Since I don't have access to a specific product database for "Tiger Racing On-Road Boots G3," I'll describe the typical features you'd find in a good pair of on-road motorcycle boots, using "Tiger Racing" as the brand context. These features are generally standard across reputable on-road boot manufacturers.

Here are the likely product features for Tiger Racing On-Road Boots (G3):

Primary Features (Safety & Protection):

1. Durable Outer Construction:

   • Material: Typically high-grade microfiber leather, genuine leather, or advanced synthetic materials designed for abrasion resistance.

   • Impact Protection: Reinforced areas made of TPU (Thermoplastic Polyurethane) or similar hard plastics strategically placed at:

     • Shin: Large shin plate to protect against impacts from debris or the bike itself.

     • Ankle: Internal and/or external ankle braces or protectors to prevent twisting and impacts.

     • Heel: Strong, reinforced heel cup for impact absorption.

     • Toe: Hard toe slider (often replaceable) and reinforced toe box to protect against impacts and abrasion during slides.

2. Integrated Ankle Support: Often includes internal bracing or an articulated system to allow forward/backward movement for shifting/braking while preventing excessive side-to-side twisting.

3. Oil/Fuel Resistant Sole: A durable, non-slip rubber compound sole designed to provide excellent grip on footpegs and various road surfaces, even when exposed to oil or fuel.

4. Gear Shifter Pad: A reinforced, textured area on the top of the toe box (usually left foot only) to prevent wear and tear from the gear shifter lever and provide better grip for shifting.

Comfort & Functionality Features:

5. Comfortable Interior:

   • Lining: Breathable, moisture-wicking mesh or textile lining to keep feet dry and comfortable.

   • Padded Areas: Foam padding around the ankle, shin, and Achilles tendon for comfort and a snug fit.

   • Anatomical Footbed: Removable and replaceable footbed for cushioning and support.

6. Ventilation Systems: Strategically placed vents (often mesh or perforated leather) to allow airflow, crucial for comfort during warmer rides, especially in climates like Nairobi's.

7. Closure System:

   • Zipper: Often a full-length side zipper (YKK is common) for easy entry and exit.

   • Velcro Flap: A large Velcro flap (often covering the zipper) for a secure, adjustable fit and to keep debris out.

   • Ratchet or Buckle Closures: Some models, especially those with a sportier or race-oriented design, might include additional ratchet buckles for a very precise and secure fit.

8. Flex Panels: Accordion stretch panels (often above the ankle and at the Achilles) made of flexible material to allow natural movement for walking, shifting, and braking, without compromising protection.

9. Water Resistance/Waterproofing (Model Dependent):

   • Some on-road boots are designed to be water-resistant or fully waterproof, often incorporating a breathable waterproof membrane (like a generic "waterproof lining" or a branded one if specified). This would be a premium feature.
