That's really disappointing. I was referred there (OK, long time ago, 2004) by my GP. I'd ruptured a tendon in my foot, classic symptoms, but quite complicated to diagnose and treat.
My GP sent me to them, they confirmed diagnosis, bound up foot and gave me crutches (instantly supposed to be non-weight bearing) organised MRI scan to confirm then referred me to brilliant surgeon who (amongst other things) looked after the feet of Darcey Bussell - so knew what he was doing!
I had surgery and went back to them post-surgery for rehab, physio and orthotics. They were, in those days, very impressive. I wasn't running then, so don't know if they had any specialists, but I did have a sporting background, and so did they, across a number of sports, so they all had a vested interest in getting me back to health ASAP.
