The outsole can be made from separate materials with different properties.
Most work boots have a dual density structure, usually two different types of materials.
The external material is a harder wear-resistant layer, while the interior is softer and provides a cushion along the entire foot bed.
The footbed is the inside bottom of the boot, directly under the soles of the feet, called the sock lining.
The insole is connected to the \"last\" edge of the upper, and during the final assembly, the insole is wrapped at the \"last\" edge during the boot closure.
The footbed is made of a kind of cardboard or synthetic cardboard.
Many boots have removable and replaceable foot beds, so it can be adjusted for the wearer who needs additional support to help handle the natural shape of the foot or the positioning defect of the foot when standing.
