Size Guide


The M-WRAP™ medial wrapped midsole designs provides rearfoot stability for workers with flater feet and those that wear orthotics or arch supports. The heal wraps on the medial side providing a stiffened structure helping to reduce the collapse of the footwear medially and also mitigate roll.
Our Hydrodynamic™ sole is high friction sole where the channelling varies consistently across the sole based on the pressure pattern of the foot to maximise the fluid dispersion from underneath the foot. Three distinct levels of channelling appear on the sole; The Primary channel is very deep to remove the bulk of the contaminants with sceondary and tertiary channels providing more leading edges to further assist in the process.
Combining Kevlar stitching, fire retardant lacing, full leather upper and Penetration Resistant midsole, the CHASSIS is purpose built for those exposed to sharp objects and hot material in construction and heavy industry.

Medial wrapped midsole design provides rearfoot stability for those that need it. Particularly important for people with flat feet and those that wear orthotics or arch supports.
Sole shape and tread pattern engineered to optimise fluid dispersion beneath the foot to minimise slips.
Heel shaped to match the natural heel strike position during walking to maximise contact area and provide a smooth ride.
Breathable memory foam insole that moulds to the foot providing a customised fit and helping to reduce in-shoe friction.
Constructed on cushioned foam insole board for a smooth ride.
Flex groove along the length of the sole to provide flexibility to allow a smooth transition from initial contact to foot flat and improve terrain adaption.
Manufacturing technique used to improve the breathability of leather and lining materials.
Specifically compounded phylon midsole to improve cushioning rebound characteristics and durability.
Sole design feature to provide support on the lateral side, particularly when used with foot orthotics.
Wide anatomical shaped toecap to reduce rubbing and nerve impingement.
