The Materials


Nubuck Leather

Sanded or buffed into a velvet-like finish, our premium Nubuck Cowhide Leather is sourced from a leading, environmentally responsible New Zealand tannery and made to last.


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.



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.


TPU Outsole
