Product overview
About chunky lug-sole boots
Chunky lug-sole boots are defined by an oversized, deeply cleated sole under a sleek lace-up upper. The reference shows black leather with eyelets and speed hooks, a padded collar and a chunky lug sole with a grey midsole line.
The sole drives the look and the cost. Stock chunky soles are available from sole makers; custom soles need moulds in every size. Sole weight is a design consideration, so EVA-filled or lighter compounds may be used.
OEM: your design
Send your tech pack and sole reference; we source the sole or quote tooling.
ODM: developed with you
Share references; we propose chunky sole families and develop the upper.

Branding that needs tooling
- Embossed logos. Heat and pressure with a metal die raise the logo on leather or synthetic.
- Debossed and heat-stamped logos. A die presses the logo into the surface, optionally with foil.
- Logo moulded in the outsole. Requires a new or modified outsole mould; only with custom sole tooling.
Custom lasts, outsole moulds, cutting dies and branding tools may add tooling costs and raise minimum quantities. They are quoted separately before you commit.
Sizing and specifications
Sizing and technical specifications
Size conversions are approximate and vary by last and brand; they are not a production grading chart, and your own brand size chart replaces them if you have one. Technical measurements are set on your last and samples, recorded on the approved sample and controlled in bulk.
Often unisex. The heavy sole affects how the boot flexes and fits at the heel, checked on wearers.
