The TReK Welder Boot is a robust and comfortable welding boot designed for demanding tasks in welding, construction, skilled trades, and heavy industry. Its durable leather upper is paired with a strong, certified ProNose, providing extra protection when working in a kneeling position.
The welding boot is approved for welding operations under EN ISO 20349-2:2017+A1:2020 and is CE-certified according to EN ISO 20345:2022+A1:2024 with classifications S3S, HRO, SC, FO, WG, LG, and SR. This makes the TReK Welder Boot a safe choice for professionals requiring protective footwear in demanding work environments.
Robust protection for welding and heavy-duty work
The HRO-tested, slip-resistant nitrile rubber outsole is designed to withstand high temperatures and provide stable footing. The outsole also features a ladder grip and a specialized shank, which enhance stability while reducing twisting and strain around the heel.
The TReK Welder Boot features an NRGize Core PU foam midsole, delivering effective shock absorption and flexibility during work. This makes the boot ideal for workdays involving extensive standing and movement on hard surfaces.
A practical Velcro closure allows for quick and easy adjustment, while the breathable, moisture-wicking mesh lining helps keep feet comfortable throughout the workday.
Comfort and ergonomics
The soft insole, made from bio-based foam, provides additional shock absorption and support. The combination of a flexible midsole, stabilizing shank, and ergonomic design makes the TReK Welder Boot a comfortable choice for long workdays.
The boot features a composite toe cap and fiber puncture-resistant midsole, providing protection without the need for traditional steel components.
