Hi gothbound
Thighboots2 is quite correct, this is repair is "Very Routine" & all in a days work for a cobbler.
I would say that it is a 50/50 split between shoes that come in with a nice "easy" to remove pin & shoes like yours that have gone just a bit to far!
Timpson will repair these with no problems, so to will any independent repairer who works for him self & may offer that "something" extra in customer service.
