Metal-Free Protection Without the Weight

The Puma Krypton Blue Mid Safety Boot brings something different to the table – serious S3 protection without the bulk. Built around Puma's naturalFLEXMOTION® sole technology, these boots move with you rather than against you. If you're spending long shifts on industrial floors or navigating warehouse aisles, the difference is noticeable from hour one.

Key Features:

• naturalFLEXMOTION® Sole Architecture: Combines the Natural Running concept with safety boot engineering. Your feet move naturally, the boot flexes with every step, and the double-density PU sole with iCELL cushioning absorbs impact on concrete and hard surfaces.
  
• Composite Fiberglass Toe Cap & FAP® Penetration Protection: Complete metal-free construction. The composite cap protects against impacts, whilst the flexible FAP® midsole guards against punctures from below. Airport-friendly and lighter than traditional steel.
  
• S3 Safety Rating with ESD Protection: Meets full S3 standards for industrial environments. ESD properties prevent electrostatic discharge – essential for electronics assembly and anywhere static-sensitive equipment is present.
  
• Oiled Nubuck Leather Upper: Durable black and blue construction that looks professional and handles the rough stuff. TPU reinforcement at the toe and heel adds extra protection where boots take the most punishment.
  
• BreathActive Lining & evercushion® BA+ Footbed: Open-pored foam actively transports moisture away from your feet. The functional lining manages humidity throughout the day. No swampy boots by lunchtime.
  
• Wafer-Profile Outsole: Specially developed tread pattern guarantees optimal grip on flat industrial floors. The slip-resistant sole keeps you stable when moving quickly around machinery or carrying loads.
  
• Extended Size Range: Available in sizes 40 to 49, including larger sizes that are often hard to find in safety footwear.
  

Ideal for assembly work, craft trades, general industry operations, and warehouse logistics. Puma Safety's Krypton Blue Mid delivers the protection standards you need with the flexibility and comfort you actually want. DGUV 112-191 certified for use with orthopedic insoles if you need customised support.
