In industries like metallurgy, smelting, and glass manufacturing, workers are exposed to radiant heat and molten metal splashes. Modern thermal protection shoes now incorporate Nitrile Rubber outsoles capable of withstanding 300°C contact heat.
Global logistics and cold storage expansion have driven the demand for CI (Cold Insulation) rated footwear. Utilizing Thinsulate™ linings and aerogel insoles, these shoes maintain internal temperatures in environments as low as -40°C.
Procurement departments are moving away from "cost-only" sourcing toward "trust-based" sourcing. Adherence to EN ISO 20345:2022 is no longer optional but a prerequisite for entering the European and American markets.
How Weifang Lento and top exporters are defining the next generation of PPE footwear.
The roadmap for thermal protection shoes is pivoting toward Phase Change Materials that absorb or release heat to maintain a constant micro-climate inside the shoe. Additionally, the transition from solvent-based adhesives to Water-based Cold Bonding and Desma Injection technology reduces the carbon footprint by 30% while increasing the lifespan of the thermal bond.
Weifang Lento Shoe Co., Ltd., located in Weifang, Shandong, is a leading manufacturer in the field of personal protective footwear. We specialize in producing high-quality work shoes, safety shoes, work boots, safety boots, and custom private label shoes.

We provide localized regulatory compliance consulting for the EU (CE), USA (ASTM), and Australasia (AS/NZS). Our team assists distributors in navigating complex tariff codes and import documentation.
Custom branding is at our core. From specialized outsoles with your logo to proprietary thermal liners, our R&D center transforms your conceptual designs into certified safety footwear.
With an annual capacity of over 1.2 million pairs, Weifang Lento ensures stable lead times. We utilize AI-driven inventory management to mitigate global shipping fluctuations.
In the age of Google's AI Overviews, the most successful factories provide unique data points. This includes lab test results for thermal degradation, abrasion resistance charts of TPU vs. Rubber, and ergonomic impact studies. Weifang Lento provides these data packets with every bulk order, ensuring our clients have the "information increment" needed to outsell competitors.
Q: What is the difference between HI and CI ratings in thermal shoes?
A: HI (Heat Insulation) measures the shoe's ability to resist temperature rise inside the shoe when exposed to heat, while CI (Cold Insulation) measures the resistance to temperature drop in cold environments. Both are tested according to EN ISO 20345 standards.
Q: Can thermal protection shoes be lightweight?
A: Yes. By using composite toes instead of steel toes and advanced Kevlar midsoles, we significantly reduce weight without compromising the thermal barrier or safety protection.
Q: What is the minimum order quantity (MOQ) for custom thermal boots?
A: Generally, our MOQ starts at 500-1000 pairs depending on the level of customization. For stock items, we offer more flexible options for trial orders.
Q: How do you ensure the shoes meet CE and ASTM standards?
A: Every batch undergoes rigorous internal testing in our CNAS-certified lab, followed by periodic third-party audits from organizations like Intertek or SGS.
