Flame-resistant Nomex laces with emergency opener for rapid release under operational conditions. Dividable zip allows easy cleaning of the boot interior.
Waterproof and breathable lining with 3D mesh upper edge for optimised airflow — holds inside-shoe temperature to +5°C increase.
Reinforced upper flexibility with double flex zone in heel and instep — provides maximum stability without sacrificing mobility on uneven terrain.
Carries WR (water resistance), HRO (outsole heat resistance), HI3, CI, AN and SRC — a full structural rating complement for interior attack environments.
Integrated RFID for boot identification, PPE inspection records and service life tracking across brigade fleets.
The zip system is exchangeable — a service feature that extends boot life by allowing replacement of the entry mechanism rather than the whole boot.
Both carry similar F2A structural ratings with Sympatex® Moisture-Tec® membrane. The Primus 22 (Ref 33322) has a 23 cm shaft height and weighs approximately 1,150 g. The Voelkl ONE (Ref 33331) has a taller 29 cm shaft and weighs approximately 1,370 g — providing more leg coverage for interior attack. The Primus 22 offers a more compact profile suited to environments where lower shaft height is preferred.
Yes. The Primus 22 features an exchangeable zip system — the zip can be replaced by an authorised service partner, extending the operational life of the boot without requiring full replacement. Contact us for Voelkl service options in your country.
Yes. The Primus 22 carries WR (water resistance) rating under EN ISO 15090:2012 — the boot is tested to resist water penetration under defined conditions. The Sympatex® Moisture-Tec® membrane provides the internal waterproof barrier, while the full-grain leather upper adds an additional moisture barrier.
HRO (Heat Resistant Outsole) means the outsole has been tested to resist brief contact with hot surfaces. This rating confirms the outsole maintains integrity when in contact with surfaces at defined high temperatures — an important protection characteristic for interior structural firefighting where floors may be superheated.
