**Upper Material:** Crafted from black荔枝纹 (Lychee-grain) top-grain cowhide or microfiber leather. It features excellent abrasion resistance, tear strength, and oil repellency, as well as water-resistant and splash-proof properties, making it ideally suited for the complex and demanding environments of construction sites.

**Thermal Design:** The interior is lined with plush material (simulated lamb's wool / thickened fleece) to effectively lock in heat and provide insulation against the cold. This design is suitable for outdoor work in low-temperature conditions ranging from -10°C to 0°C.

**Protective Features:** Equipped with a built-in steel toe cap designed to withstand impact forces of up to 200 Joules, thereby protecting the feet from injuries caused by falling heavy objects. It also features a standard anti-puncture midsole—available in either Kevlar or steel plate options—to prevent injuries to the soles of the feet from nails or other sharp objects.

**Sole Design:** Features a black rubber or PU outsole with a deep-lug, anti-slip tread pattern. This design offers exceptional abrasion resistance, slip resistance, and resistance to acids and alkalis, ensuring stable and secure footing even on icy, wet, or oil-slicked surfaces.

**Footwear Style:** A high-top, lace-up design that fully supports and wraps around the ankle. This configuration prevents foreign objects from entering the shoe and helps guard against sprains, thereby enhancing both overall protection and the secure, supportive fit.
