Actually, I hadn't read renatele's post carefully - I thought it was an unconfirmed rumor.
My Klings are breaking down, but they've had 11 years, thousands of hours on the ice, and some deliberate extra physical, chemical and thermal extreme efforts to break them in. Mine didn't fit, but I blame that on the outside fitter, not the company. When I came up to their factory store 5 or 6 years later, they rebuilt them for free, and tried in vain to make them fit - no charge.
Everything about Klingbeil boots bespeaks quality, and everything about my interactions with Don and company bespoke a total commitment to service, along with an extraordinary amount of knowledge and experience.
The community of expert custom skate boot makers is extremely small. It's possible they contacted all the ones that were at loose ends, if there were any, and no one was interested. Perhaps they also didn't want the family name attached to someone less expert, or who would provide poorer service.
