LYTOS PROFESSIONAL WK-3409 are lightweight trekking-style work and rescue boots designed for long-term use in demanding, steep terrain. They are suitable for professional work, rescue services and movement in mountain environments.

The upper is made of 2.4–2.6 mm hydrophobic nubuck leather and features a substantial rubber rand that protects the footwear against abrasion and damage. The directly laminated membrane provides waterproofing and good breathability, while also protecting against the penetration of blood and bodily fluids.

The sole combines an EVA midsole and a nitrile rubber outsole. It offers shock absorption, high slip resistance and resistance to oils, hydrocarbons and contact heat up to 300 °C. The boots also feature ESD properties, ankle protection and textile puncture protection.

Availability: The most common sizes, 42–47, are normally stocked in the Czech Republic. Other sizes in the 35–49 range are available to order from the supplier's warehouse in Italy.
