تولید زیره کفش 👏👏👏/How made The outsole of shoes

The outsole is the layer in direct contact with the ground. Dress shoes often have leather or resin rubber outsoles; casual or work-oriented shoes have outsoles made of natural rubber or a synthetic material like polyurethane. The outsole may comprise a single piece or may be an assembly of separate pieces, often of different materials. On some shoes, the heel of the sole has a rubber plate for durability and traction, while the front is leather for style. Specialized shoes will often have modifications on this design: athletic or so-called cleated shoes like soccer, rugby, baseball and golf shoes have spikes embedded in the outsole to improve traction
