    Benefit: Ideal for people occasionally stepping on hot surfaces/objects while working.

    What is it: Australian Standards 2210.3:2009 Additional Classification. Resistance to Hot Contact. Outsole does not melt, char, crack or craze when coming in contact with 300ºC surface for one minute.

    Where is it: Outsole

  • SRA: Slip Resistant with Water on Ceramic Tiles

    Benefit: Provides sufficient slip resistance to prevent a fall when working on soapy wet tiles.

    What is it: Australian Standards 2210.3:2019 Additional Classification. SLS (soapy water) solution on ceramic tile test. Slip resistance coefficient only heel contact is > 0.28, and slip resistance coefficient with whole shoe flat contact is > 0.32.

    Where is it: Outsole

  • Safety Toe 1.5 ton Compression

    Benefit: Protects toes by providing a minimum clearance when something runs over them.

    What is it: Australian Standards 2210.3:2009 Standard. Compression test where a 15kN force is gradually applied to the toe, tested by an independent and authorised laboratory and then certified by SAI Global.

    Where is it: Toe

  • Safety Toe 200 Joules Impact

    Benefit: Protects toes by providing a minimum clearance when a large object falls on it.

    What is it: Australian Standards 2210.3:2009 Standard. Tested with a drop strike test machine with a 200 Joule force by an independent and authorised laboratory and then certified by SAI Global. Note that the Australian standard is higher than the US standard.

    Where is it: Toe

Outsole

  • Oil Resistant Rubber

    Benefit: Oil and abrasion resistant

    What is it: Specially formulated vulcanized rubber, custom shaped with a tread pattern

    Where is it: On the bottom of the shoe where it contacts the ground.

Cushioning

  • Arch Support Insole (PU)

    Benefit: Arch support insole with increased arch support and more cushioning. Longer lasting than other insole materials. Removable, and so able to be replaced with orthotics if needed.

    What is it: Polyurethane sponge formed to cup around the heel and under the arch (thicker under the arch than our normal arch support insole providing more support).

    Where is it: Inside the shoe, directly under the foot.

  • INSULON®

    Benefit: Cushions and absorbs shock that over time causes bone and muscle trauma.

    What is it: Specially formulated long lasting, soft foam material

    Where is it: Typically placed within the midsole of the shoe underneath the foot, in the heel and forefoot areas.

  • PORON®

    Benefit: High shock absorption, low compression (long lasting cushioning)

    What is it: Specially formulated foam material by PORON.

    Where is it: Placed directly under the insole inside the shoe in high impact areas in the forefoot and the heel.

  • PU

    Benefit: Provides and excellent balance of shock absorption (cushioning) and energy return (rebound). These cushioning and rebound properties are longer lasting than other cushioning foams.

    What is it: Polyurethane sponge.

    Where is it: The midsole of the shoe, which is the part under the foot, between the outsole and the upper.

Stability

  • ExoFrame

    Benefit: Supports the ankle and holds the heel firmly in place, providing excellent stability when the foot first strikes the ground. A firm heel counter is essential for fundamental support and stability.

    What is it: Rigid plastic material that is shaped to match the contours of your heel.

    Where is it: Inside the upper part of the shoe, surrounding the back and sides of the heel.

Upper

  • Composite Safety Toe Cap

    Benefit: 200 Joule impact & compression protection. Lighter than steel and provides superior insulation properties. Airport friendly.

    What is it: Epoxy fibreglass. Complies with all the Australian standards for Type 1 impact resistance and compression resistance (AS/NZS 2210.3:2009).

  • DRILEX® Lining

    Benefit: Wicks sweat away from the foot, and its anti-bacterial properties control odour inside the shoe.

    What is it: Specially treated textile lining (patented technology by DRILEX).

    Where is it: Inside the upper of the shoe. The lining is the part of the upper that is closest to the foot.

  • TPU Scuff Cap
