Innovative Infinergy technology and comfort
Experience the revolutionary Infinergy technology in the sole, which returns 55% of the energy with every step. Its specially developed composition offers exceptional flexibility, resistance to extreme temperatures from -20°C to +40°C, and outstanding shock absorption. Meanwhile, the anatomical U-POWER Original footbed distributes your weight evenly across your foot for all-day comfort.
Putek® Plus durability and Boa fit
Protect your feet with waterproof Putek® Plus fabric, offering superior abrasion resistance. The smart Boa lacing system lets you adjust the fit in an instant with a simple dial, ensuring stability without uncomfortable pressure points. Plus, the Air Toe aluminum toe cap keeps your feet cool thanks to its integrated membrane.
Complete ESD protection and slip resistance
Work with confidence in any environment thanks to ESD certification, which prevents the build-up of electrostatic charges. The non-metallic midsole provides full puncture protection, while the PU outsole is SR slip-resistant, antistatic, and resistant to oils (FO). In addition, CI cold insulation effectively protects you from the cold during outdoor work.
