Sole System Construction

VANGUARD® Direct-Attach Construction

A highly advanced soling method that permanently fuses the leather upper of the boot to the entire outsole system to produce a boot that is lightweight, flexible and extremely durable. During this process, the polyurethane midsole material is poured into a mold and adheres to the upper, forming a permanent bond during the cooling process.   A premium VIBRAM® rubber outsole is then attached to the midsole to complete the process.   Boots made using the direct-attach construction can be resoled.

Cement Construction

A process frequently used in running shoe construction, cement construction is when the outsole of the boot is glued to the leather upper. Boots made with a cement construction are typically lighter in weight and offer a great deal of flexibility; however, cannot be resoled.
