At approximately 940 g per boot, the Rescue Pro STX is the lightest Voelkl model in the range — engineered for technical rescue teams who need to move quickly over extended periods.
Anatomically shaped aluminium toe cap rated to 200 J impact — lighter than a comparable steel toe cap, without sacrificing impact protection. Abrasion-resistant overcap extends toe durability.
Quick-entry lacing with a fully opening zip for easy cleaning and fast donning. Interchangeable laces allow field replacement without boot servicing.
74% less moisture and 45% less heat than leading technologies. The membrane also protects against viruses and bacteria — an important characteristic in medical rescue environments.
Rust-proof spring steel midsole resists penetration from below — protecting against sharp debris in technical rescue environments such as building collapse and vehicle extrication scenes.
Integrated RFID for boot identification, PPE inspection records and service life tracking — supporting compliance and audit requirements for rescue unit PPE fleets.
The Rescue Pro STX is certified to EN ISO 20345:2012 S3 — the high-performance industrial and rescue safety footwear standard — rather than EN 15090 (the firefighting boot standard). It is designed specifically for technical rescue, emergency response and rescue unit personnel who need a lightweight, high-performance boot for extended rescue operations rather than structural fire interior attack. For structural firefighting certification, we recommend the Voelkl ONE, Primus 22, or Kommandant Pro.
An aluminium toe cap provides the same 200 J impact protection as a steel toe cap at significantly less weight — contributing to the Rescue Pro STX's exceptional 940 g target weight. For technical rescue teams who may wear their boots for 12–24 hour shifts across difficult terrain, this weight saving meaningfully reduces fatigue. The aluminium toe cap is shaped anatomically to the foot for comfort and fitted with an abrasion-resistant overcap for field durability.
The Sympatex® Moisture-Tec® membrane acts as a barrier not only against water and contaminants but also against viral and bacterial penetration through the lining. This is relevant in medical rescue environments, mass casualty incidents, and situations where personnel may be exposed to biohazardous materials — providing an additional layer of foot protection beyond standard waterproofing.
