Wooden soles will show some wear and tear from daily use. But they are very durable and can be restored to their original glory with some professional care. 
 
This services covers damage like scratches and dents in wood soles. For scratches we sand the area and add a clear sealant to protect the wood. For larger dents, we add wood filler, sand, and seal.

Protective sole option: add a thin rubber overlay on your existing leather soles to guard against premature and uneven wear. It will also improve grip and prevent slipping.
