The Materials

Full Grain Leather & Nubuck Leather
Each Leather is specifically chosen to ensure the style of boot is fit for purpose and is ethically and environmentally sourced from members of the Leather Working Group (LWG).

Baltico® Lining
A soft, non-abrasive, hydrophobic material that wicks perspiration away from the foot, enabling the skin to remain cool and dry.

Ortho Rebound® Footbed
Our patented Ortho Rebound® Footbed is uniquely designed to reduce foot fatigue. Made from high quality Polyurethane, it always retains its shape and thickness to ensure support from heel to toe, is antifungal, and the high wicking material keeps your feet cool and dry.

Poron
Strategically placed high-tech Poron® pads are placed in the sole and under your foot’s peak stress areas. We included Poron® in our Trisole® Comfort Technology, which is now the benchmark for safety boots.
