RENZO is perfect

Nothing is 100% safe - but this safety boot comes pretty close. The RENZO Biomex GTX BOA® blue Mid ESD S3 has a solution for anything and everything. Ground strewn with rubble and boulders? The PU/PU SAFETY-GRIP sole ensures a sturdy step. Bad weather? No problem for the upper made of hydrophobised cowhide and nubuck leather. Even better: thanks to the GORE-TEX Performance Comfort Footwear on the inside, protection from penetrating moisture is guaranteed at all times. Falling rocks? The steel toecap withstands all impacts without a problem. Nails in the subfloor? The steel midsole provides impenetrable protection. Hectic on the building site? The BOA® Fit System allows quick donning and doffing. Also an item on the list: BIOMEX PROTECTION©. Thanks to this joint-stabilising cuff, you can jump off the excavator and not worry about injuries, as the cuff puts an end to ankle sprains. Just as the PU point protection prevents premature wear and tear. Did we forget anything? Hardly. Excellent slip resistance is present anyway, and it is also ESD-compatible. This exceptional boot is SR-certified.

Features

  • ESD: ESD-approved safety and occupational footwear thus not only protects people, but also serves to protect electrostatic hazard-running construction parts and building groups.
  • PROTECTION AGAINST PENETRATION: The penetration-protecting midsole prevents objects from penetrating through the sole.
  • REFLECTING MATERIAL: Reflective materials which optimise visibility in dark environments.
  • ORTHOPEDICAL FOOT PROTECTION: The shoe is certified for orthopaedic adjustments according to DGUV Standard 112-191. An orthopaedic shoemaker of your choice can make a number of orthopaedic adjustments tailored to your personal situation, such as orthotics, without the shoe losing its protective function and standard.
  • GORE-TEX® MEMBRAAN: GORE-TEX® acclimatising membranes permanently protect your feet from wetness, are extremely actively breathable and offer optimal climate comfort.
  • BOA® Fit System: BOA® is an innovative closure system without laces, buckles or Velcro fastening, which stays in place all day without slackening.
  • LWG: ELTEN GmbH leather products support responsible production through Leather Working Group.
