It has taken nearly two years to find someone who can add a 2cm raise to one of my shoes - Original Cobblers have done a perfect job! I would recommend them to anyone who needs this type of work on their shoes.
The process was simple. I posted a shoe that needed a raise together with an old shoe that had a raise, and 10 days later my new raised shoe came back. I'm now looking for a new pair of shoes to send to Orignal Cobblers.
