Composition
The Materials
Full Grain Leather & Nubuck Leather
Each Leather is specifically chosen to ensure the style of boot is fit for purpose.
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.
TPU Outsole
Our standard durable outsole with heat resistance to 130°C.

Slip & Oil Resistance
All Steel Blue footwear is designed to exceed the Slip resistance requirement in both the AS 2210.3 and EN ISO 20345. Our boots are rated as SRC which means that the footwear has been tested in laboratory conditions on both a ceramic tile floor with a Sodium Laureth Sulfate solution (SLS) and on a steel floor with Glycerine.
Anti-Static
Prevents the build-up of static electricity within your body by dissipating it through the sole.
Water Resistant
A special tanning process treatment means all Steel Blue boots are water resistant.
Scuff Cap
An abrasion resistant, streamlined toe cover that covers more of the boot.
Zip Sided
