DICKIES TECHNOLOGY WELTED SOLE
Named after Charles Goodyear, inventor of the machinery used to produce this construction in 1896. Renowned for its comfort and durability, the Goodyear
Welted construction is used on our premium, heavy duty safety footwear.
A leather or synthetic strip known as a “welt” is stitched to the upper and insole, holding the 3 components securely together and giving shape and strength
to the product. The attachment of the welt creates a cavity underneath the insole, which is filled with foam. As well as filling the cavity, this also benefits
underfoot comfort.
A thin midsole of EVA or similar is cemented to the underside of the lasted boot and a row of stitching applied through the welt and midsole. This thread is
visible on the finished product. Finally the outsole is bonded to the midsole and the sides sanded back to achieve a neat finish.
The stitching of the midsole to the welt means that should it be necessary, the midsole and outsole can be removed, repaired or replaced without destroying the
boot.
Upper

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

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.
Insole
An internal component that the upper and welt are stitched
to, forming the upper part of the shoe before the sole is
attached.
Stitching
A strong thread attaching the welt to the midsole.
Welt
A strip of material that joins the upper to the sole.
Foam Filler
Fills the cavity created by the welt and provides additional
underfoot comfort.
Anti-Penetration Insert
A metal or composite insert which prevents puncture from
sharp objects though the bottom of the footwear.
Midsole
