If you live in England, here is the best boot-fitter available:
'Dave The Boot': -
28 Holywell Hill
It is essential that people book a boot fitting in advance with Dave as he has a long waiting list. He will not sell boots to people if he knows they are going to receive heavy use within 2 weeks of purchase, as they will not have been worn in properly. He adheres strictly to a boot fitter's code of practice.
