DICKIES TECHNOLOGY INJECTED SOLE
DTI is our new dual density, direct injected Polyurethane (PU) sole. Developed exclusively by Dickies, it comprises of a durable, abrasion resistant outsole and a
softer cushioning midsole, which is moulded directly onto the bottom of the boot, providing a strong bond between upper and sole.
The midsole cradles the upper, providing increased protection, with a large scuff cap over the toe and raised areas along the sides and heel.
The tread configuration has been specifically designed to provide supreme performance and grip in a wide range of conditions. The combination of large areas
of ground contact, together with deep angular grooves, gives traction in both rough terrains and flat smooth surfaces. Slip testing has proven this sole to
perform to a high standard and is SRC rated.
The bottom of the cleats have been rounded slightly to prevent flex cracking and help release dirt and grime.
The waist area includes ladder grip lines for working at heights. The sole is highly resistant to oils and fuels.
Upper
The part of the shoe that covers the
foot. Can be constructed from a range
of materials to provide the required
protection, climate control, waterproofing
and design aesthetics. Usually consists of
components which are stitched together to
form the 3D shape.
Toe Cap
A metal or composite material, this
protects the wearers toes as well as
helping to maintain the structure of the
footwear.
Insock
A layer of cushioning material that sits
inside the shoe, to provide underfoot
comfort. Sometimes removable.
Anti-Penetration Insert
A metal or composite insert which
prevents puncture from sharp objects
though the bottom of the footwear.
Midsole
A layer of moulded light weight material
which provides shock absorption at heel
strike and propulsion at launch during the
walking cycle.
Outsole
The part of the sole that comes into
contact with the ground. Provides grip
and stability during walking and protects
against wear and tear. Can be moulded in
a variety of materials.
WHAT IS PU?
Polyurethane is a combination of Polyols & Isocyanates. When mixed together during the moulding process, a chemical reaction
occurs and the Isocyanates cause the Polyols to expand and fill the sole mould.
The rate of expansion can be controlled. The more Isocyanate added, the quicker the expansion occurs, increasing the amount
of air in the material. This can make the soles softer and more flexible, but also weaker. It is therefore important that the correct
density of compound is used and a good balance between hardness and strength is achieved.
