U-Power Performance S Safety Ankle Boot S3S Cold Insulated

Cold Storage and Winter Sites — This Boot Handles Both

When you're working in a cold store, outdoors in January, or anywhere wet and unforgiving, your footwear has to do a lot of heavy lifting. U-Power's Performance S from the Concept M range is built for exactly those conditions. It keeps your feet warm, dry, and protected through long shifts — without making your feet feel like they're stuck in a brick.

Key Features:

• S3S CI FO SR Protection: Certified to EN ISO 20345:2022 — that's composite toe protection, anti-puncture insert, fuel oil resistance, and superior slip resistance all in one boot.
  
• AirToe Composite Toecap: Nickel-free composite toecap — lighter than steel, no cold transfer, and no skin reactions for those sensitive to nickel.
  
• Thinsulate Thermal Insulation (CI): Cold insulation rated, so your feet stay warm without piling on bulk. Ideal for cold storage, fridges, and outdoor winter work.
  
• Full Grain Water-Repellent Leather Upper: Keeps water out from the start. Smooth leather that shrugs off rain, puddles, and wet surfaces.
  
• Action Dry Breathable Lining: Moisture-management lining pulls sweat away. Warm but not sweaty — a tough balance, and U-Power nails it here.
  
• Save&Flex Sole Technology: The sole flexes naturally with your foot. Less fatigue on long shifts, especially if you're on your feet all day on assembly lines or outdoor sites.
  
• Natural Comfort 11 Removable Insole: Ergonomic insole you can swap out if you use custom orthotics. A small detail that makes a real difference over a 10-hour shift.
  
• Nickel-Free Throughout: Hardware and components are all nickel-free — important for workers with metal allergies.
  

U-Power's Performance S is a serious bit of kit for anyone who needs cold protection, slip resistance, and all-day comfort in one lace-up boot. Available in EU 38–47 (UK 5–12). Order yours at Glovesnstuff today.
