Built for the Harshest Sites — Without Weighing You Down

Construction sites, road works, port yards — these environments chew through cheap boots fast. The U-Power THANOS S ESD is built differently. It combines serious protection with a boot you can actually wear all day, thanks to smart engineering that tackles cold ground, sharp debris, and low-light hazards all at once.

Key Features:

• S3S CI FO SR ESD Certified: Fully certified to EN ISO 20345:2022, covering steel-free toe protection, cold insulation, fuel oil resistance, slip resistance, and ESD compliance (IEC 61340-5-1:2016 & IEC 61340-4-3:2017). That's a lot of boxes ticked in one boot.
  
• AirToe Composite Toe Cap: Lightweight and completely metal-free. Walks through security scanners without a second thought, and won't conduct cold the way steel does on a freezing site.
  
• Save & Flex® PLUS Anti-Puncture System: All-fabric construction means it flexes naturally underfoot — none of that stiff, rigid feeling you get with traditional midsole plates.
  
• Cold Insulation (CI) Rated Outsole: When you're standing on frozen ground or cold concrete for hours, the CI-rated sole keeps the cold from creeping up through your feet.
  
• Pull-Up Leather Upper: Water-repellent, abrasion-resistant, and tough enough to handle the daily battering of a construction or agricultural environment.
  
• WingTex Air Tunnel Lining: Breathable inner lining that keeps air moving — feet stay drier during long shifts without sacrificing warmth.
  
• Retro-Reflective Lateral Inserts: Silver reflective panels on the sides make you visible in low light — useful on early starts, late finishes, and roadside work.
  
• Removable Anti-Bacterial Insole: Take it out, clean it, swap it for the optional SECOSOL® orthopaedic insole if you need extra foot support during long days on site.
  

U-Power's THANOS S ESD is the kind of boot that earns its keep on a serious worksite. Certified, comfortable, and genuinely tough — available in EU sizes 38–48. Order yours at Glovesnstuff.
